S8+ recent apps blank - Samsung Galaxy S8+ Questions & Answers

After my phone has been on for about an hour, the recent apps go blank. It's usually a light color, which is particularly annoying because I have a dark theme. Has anyone else had this problem and if so how do I fix it?

Status bar menu and icons turned grey?!

I was wondering if anyone has had this happen before? I was just on my Captivate checking a few apps out and then all of a sudden the screen froze for a few seconds and all the icons disappeared and only the wallpaper was left displayed. During that time I was tapping the screen and whatnot wondering what happened and it stayed frozen like this for maybe 30 seconds before it finally came back to life, but I then noticed that whatever icons were displayed on the left side of the status bar turned grey and also when I pull down the menu from the bar it is also grey in color now.
Also I've noticed that the settings menu seems greyer as well. Does anyone have a way to fix this and bring the color back as the grey looks pretty crappy. I'm using Darky's 9.2 rom right now.
Edit: now that I'm looking at it more, it seems like ALL of the menus in all my apps now are greyed. Where before it use to be in color now everything is a dull grey?!
Can anyone help please??
Master Reset. Something (maybe a messed up app?) screwed up the graphics of your phone so if just restarting (... you DID try turning it off and back on, right?) doesn't work then just back up and master reset.
I'm guessing that you have tried rebooting, but if not try that. If that doesn't work flash to stock using Odin and if it still isn't fixed then try to get a replacement.

Issue with semi-transparent overlays

Hello.
Does anyone noticed any issues with semi-transparent overlays (alpha channel transparency).
In ES File Explorer in the address bar when it scrolls sdcard information, on both sides of the address bar it shows blinking black boxes, they are supposed to be white, simulating dissolving letters that passing under them. This doesn't happen all the time, but I'd say 80% of the time.
In SpeedTest the rectangulars under the speedometer are white covering whatever information they supposed to show.
This also happens in other application's settings, when text is too long and getting trimmed by fading away to the side, so the part that's fading away become dark colored sticking out as a broken font.
Anyone else experience this?

I've seen some text color issues, but the issues I see are the same as what I saw with my Desire HD running ICS. That being said, the speed test thing on mine works fine and I can see the boxes perfect. Did you root? Did you change to Rogers or put another RUU other than whats stock OTA on yours?
Yes, I did root and yes, it's was happening on stock rom and now on 1.82 RUU. I shall see tonight if it does the same with just fresh 1.82 without the root.
If the issue persists, what do you think could possibly cause it? (If you are certain that the boxes on each side of the speed numbers after the test are showing the graphs as supposed to)
I found what's causing it: Settings -> Developer options -> Force GPU rendering
Disabling that option fixes issue with transparency.
Any ideas if this is hardware related or software?

grey lines at top of the screen with pure black wallpaper

So recently i started to notice that in my home screen (touchwiz or other launchers) at the top of the screen there is some grey lines it is best visible if i use a black wallpaper and set the brightness to the maximum. This doesn't show anywhere except on the home screen. I tried other wallpapers, and if i look at it in the gallery or turn on ultra power saving mode there is no grey lines.(my device is galaxy s6)
Does anyone know what it is? Or how to fix it?
(i hope you guys can understand me sry for my english)
So, if you switch to your pictures and images gallery, the lines disappear?
Did you drop your device on the floor or did it incurred any damages lately?

It's a common issue. It's stupid Touchwiz/Samsung system which creates a small overlay at the top of Homescreens (any launchers) & lockscreens. In gallery etc, it's perfectly black since no overlay.
I don't think there is a fix. U can use a slightly greyish instead of full black wallpaper. It's not a big problem though
Oh i understand. Thank you for help. I was thought my phone has a problem.
Sometimes the grey lines can appear in Samsung mobiles if you use a bad launcher or a theme which is not compatible with the phone. You can try updating to a new version and see if fixes the problem, or use a light gray wallpaper as already suggested. Another couple of things to try... take a screenshot of your phone and test it on your laptop to see if the lines are still there. If not then it could be a problem with the screen itself. It's also worth restarting your phone in Safe Mode as this mode only runs with pre-installed apps. If you don't see the lines then an app could be your culprit

Weird darker bar and navigation buttons appearing over other apps

Recently I've noticed that a dark low opacity stripe has appeared on my phone, from the top to about a quarter of the top of the phone, it is constantly there, although it is a lot easier to see on darker backgrounds, and alongside it there are transparent navigation buttons on the same spot they normally are. I've already done the usual reboot, changed launchers and all that, anyone else having this problem or know how to fix it? Can't really post a picture of it since screenshotting doesn't actually show the dark areas

Every notification is grey (desaturated)

Hi
I've noticed few days ago that my notifications doesn't have colors. I mean normally app icon should be in color, like on the phone itself. But now they look like saturation was set to 0%. Even this notification thing that pops from top of the screen is grey. Every other aspect of the watch looks normal. It doesn't matter from what app notification comes from. It could be e-mail, sms, Steam or payment app. I tried to restart watch of course. It's SM-R760, running Tizen 4.0.0.7.
The icon from attached photo should have blue background.
Have you encountered something like this before? Any suggestion on how can I do something with it?
