I am experience a lot of choppiness and a screen tearing like effect with my S4 One S.
I have tried multiple ROMs and kernels none of which seem to solve the issue, however I did notice it particularly bad on CM10 ROMs. I am currently running Viper 2.0 so that's a sense based Jelly Bean 4.1 I have tried "force 2D GPU rendering" to no luck.
Basically on scrolling, particularly noticeable in the launcher screen transitions and app drawer transitions, they start off smooth, then right before the animation finishes there is a little 'jump' where it misses out the end frame or two and jumps straight to the finish. It creates a really irritating laggy stuttery sensation, which makes the phone not feel smooth to use.
I have tried all the launchers you could throw at me, currently using Holo Launcher HD because I can slow the animations right down which makes it smoother, but still has the stutter at the very end...
Is anyone else experiencing these same issues?
Sounds like you got some background app slowing the device down to a halt.
I have none of the issues you are describing, and havnt had it on any rom Ive tried either.

did you try a factory reset? it can affect wonders
maybe some roms need some time to find the right place in your phone.. my jb runs perfectly smooth after 2days and some reboots.
I always factory reset and full wipe in between flashing my ROMs.
I'm more than positive its not a bag ground process hogging CPU as I have used apps to monitor my CPU usage and it idles nice and low under 10% then shoots up during screen transitions.
I may have made the problem sound worse than it is. Its not like running the phone with the max CPU throttled down to 192MHz which does cause lag and stutter. Its more like, silky smooth everywhere, then suddenly the last frame or two of the animations skip, making it even more obvious and irritating as everything else is so smooth.
It does it with all launchers, and scrolling in apps sometimes doesn't feel smooth. ie you give it a fling, it shoots off lightning fast then as it gradually slows back down to a halt, right before the scrolling stops there is a little 'jump' or 'stutter' giving it an unsmooth feel
I'm going to try flashing a 4.2 ROM and enabling 4x MSAA to see if that will fix it. If not I might upload a video to try and capture the issue. Its almost like Vsync isn't on, or isn't working properly, but when I turn it off it only makes the screen tearing and jitter much worse!
I used AOKP 4.2 which seemed even worse than ever, it was almost like Vsync wasn't doing its job properly, then I enabled "Force 2D GPU Rendering" , "Force 4x MSAA" and "Disable HW Overlays" this greatly improved it so that it was on par with any of the other ROMs I used. However that little stutter was still there.
This ROM/Kernel supported GPU and CPU overclocking. I found out that with both cores forced to maximum speed (eg performance governor) the issues was almost completely eradicated, or extremely hard to notice. But it is just not feasable to run my phone like this. I swear I shouldn't be experiencing this stutter...
Currently running CPU1 on performance and CPU0 on badass (I am assuming CPU1 will sleep when screen is off).
Well, Im running my S with ONDEMAND governor, 1512Mhz max, 384Mhz min. I/O Scheduler is set to CFQ.
On my moms XPeria P I run SmartAssV2 / SIO, and it greatly improved both batterylife and performance on that slow-ass device
I also turned off all Window Animation things in Dev. options and turned on force GPU rendering.
Edit: These settings are applied to both cores.
Can anyone else verify with me this theory:
I switched from the ripple-effect swipe lockscreen to a more secure dot-based lock screen and since then I have not received any lag upon unlocking the device. I'm wondering if those ripple/light effects are too demanding on the cpu as it tries to ramp up thus causing some stutter/lag that people typically see. Once the governer says "OK! Ramp up the cpu freq!!" it takes a second, lag comes.. then it's gone. But switching off these special lock screen effects is much less demanding for the system to handle.
Try it, let me know what you think.
FWIW:
I'm also using Nova launcher and a slightly tweaked ondemand governer maxxed at 1.5ghz. I also have frozen a ****-ton of bloatware apps.
I seemed to get a lot more lag on 6.0 than from what I remember on 5.1.1. Tried multiple roms and they all felt the same. However after toggling in developer options "force gpu rendering" as well as "disable hardware overlays" on, this phone is like butter now smoother than ever. Hopefully this proves to help others.
Cool, I'll give.it a shot too

This did seem to make my phone faster it scores higher in quadrant too.
Still froze on game.

I'm running stock (non-rooted) and I haven't had any lag issues (yet) since updating to 6.0. App transitions especially are incredibly smooth. Still all phones get laggy eventually (I don't care what chipset or software they're running), and this is certainly worth logging for when I do have problems. Thanks.

Well, if you force GPU rendering there is a possibility that battery life may take a hit. And if you disable HW overlays you open up the possibility of rendering errors that *may* affect performance in some circumstances.
These are tradeoffs you need to weigh to make sure this will be beneficial to you or not.
I'm running TruPure XMM 2.2 and haven't had any significant lags yet and for me the settings didn't make a real difference.
I don't want to lose extra battery life on something that doesn't change anything FOR ME (=doesn't apply to everyone!).
Thanks for sharing this information though
Why Lag??

Did we all get defective chipsets??? Why are we the only ones getting lag, but the majority of people are reporting "buttery smooth" performance on Marshmallow...?
Hi guys, I saw on reddit that if you have certain Accessibility services enabled, lag and stutters will occur. For example, Dashlane's Accessibility feature slowed my phone down like crazy. After disabling it, smooth operations persisted. It's weird. I'll get the reddit link.
Edit: somehow can't share the link but I'll quote what OP said.
"I've had the Moto X Pure for two weeks now, and have been experiencing excseive stuttering when doing just about anything. The strange part was some users where experiencing lag while others weren't. Well for those experiencing stuttering while scrolling lists, try this. Go to Settings, Accessibility, and turn off all accessibility services at the top. Should fix lag!"

Zero lag on my phone. I'm running stock, though.
Those two options will cause issue with some games.
Will these settings stick through a reboot, I know the Disable HW Overlays never used to stick. It does make it noticeably smoother. I was planning on returning to LP tonight, and flashing AICP LP to get some smoothness back. It always feels like Android moves backwards when they remove features and get more and more laggy with each rendition! lol

thanks for the tip!
after switching off the accessibility service for lastpass the scrolling is much smoother again ?

I can attest to this as well actually I remember seeing that article when I was on Lollipop but I just forgot it. Appreciate the reminder it seems to have helped even further. I decided to turn off the hw overlays thing but the force gpu rendering and all accesibilty services off seems to be just as good.
I had horrible lag on everything I did on MM until I put on TruPureX rom. Now it's better than ever. Smooth as silk.
Disabling HW overlays prevents the CPU cores from assisting the GPU in rendering certain things on-screen. The build.prop already forces GPU rendering (as does stock Android) and some form of HW overlay setting.
debug.sf.hw=1
debug.egl.hw=1
debug.composition.type=c2d
These lines are in both 5.1.1 and 6.0 Pure Edition builds. Line 1 is GPU 2D rendering, line 2 is OpenGL ES HW rendering, and line 3 is Core2Duo compositing (using a multicore processor for composition, in addition to the GPU).
If you're rooted, bigger performance gains would be had by raising the throttling temps in thermal-engine-clark.conf in /system/etc. Don't go crazy, otherwise your hand or device may pay the price. Leave the 85C values alone, as the A57s will hit this quickly at 1.824GHz. But, CPU hotplug controls when the 2 A57S and 1 A53 get booted for thermal reasons. Quiet1 and Quiet0 control Cluster 1 (A57s) and Cluster 0 (A53s), respectively.
So ...
A quick test some may perform, so long as nova launcher is installed, is to open the app drawer, scroll or flick down and then immediately click home. Before these settings were applied, I constantly noticed stutter coming out of the drawer. This may seem like a silly test, but there are, in my experience, many moments of stutter in everyday use running the stock roms (my brief run of cm was noticeably smoother.)
I wouldn't say these settings insanely increased performance, but a few of the stutters I had frequently seen in the app drawer or recent menu have pretty much disappeared thus making it somewhat worthwhile.

Can you provide your settings? kinda scared to touch because idk which cpus are the a57 core0 core2 or core 4 5?
Hi fellow Mate 7 owners. I've seen mention of stuttering here before. The phone is reasonably powerful and it intrigued me as to why it stutters, especially when scrolling. It helped to remove the Huawei launcher after setting up Smart Launcher Pro and de-bloat system apps, but I still saw some stutter so turned animations to. 5, then off altogether. My phone runs quite efficiently but that minor jerkiness bothered me. I've now enabled the "force GPU rendering" setting in developer options and re-enabled animations. It runs a lot nicer. Smooth and fast.
I'm assuming the cause was just that where possible, it tries to run on the 1.3GHz economy processor which is not fast enough for frequent screen redraws where content has to be recalculated.
So, my question to those who are tech savvy with the more complex workings of Android is, can we edit something in the system that tells the phone how to control CPU governing so that it steps up to the 1.8GHz processor easier for a smoother operation?
I don't want to install an extra governor app from Google Play.
Edit:
I've ended up installing Kernel Adiutor (needs root) so that I can alter settings and see how it's affected in case it's possible to alter the kernel permanently.
Changed a few settings with CPU governor and I/O scheduler. Kept forced GPU setting in developer options and animations at 0.5.
Edit:
Uninstalled Kernel Adiutor as I had trouble with settings not all sticking and sometimes performance suffering.
I've now installed EX Kernel Manager and two good monitoring apps by same dev. Better result so far. Settings seem to stick and the phone is more reliable. It's smoother, snappy to use. Another thing this has also benefited is stable bluetooth streaming of music. I used to get dropouts, now it's like it's connected by aux cable. This is a big thing for me as I use it on BT for music a lot. It can multitask whilst streaming music and still not drop out momentarily.

Why I have to use governors that save power, this is not phone, and radiator on this tablet is finally made as it supposed to be (actually present now not absent duh), so throttling and heat is not there. Conditions have changed and we should use performance governor! After overclocking my desktop and knowing that i just put it on max frequency all the time knowing that it will be the best performance (though it auto changes power profile in inactivity)
I decided why didn't I do the same with the tablet.
I changed to performance governor and set tresholds up/down 10 points lower/higher in ex kernel for big cluster and everything running smoother, i didn't find any measurable battery toll, not that i would care about it. Though i can see it pulls significantly more current when reloading browser pages like 2000mAh. I automated this kernel profile change with franko kernel m., because I am not sure yet if to put it on permanently if it will causes standby drain, it shouldn't but it can. I find that it noticably faster with heavy tasks, not huge difference, but I I feel it, and higher amperage and seeing larger cores loaded more confirms it.
You can try and share how did it go. Anybody has other advices how to tune this kernel for performance.
