Rapid flickering in any programs randomly

Hello, I experience dizzyingly rapid flickering randomly during games or productivity apps.

It seems monitor and app dependent, one app can be flickering, alt tabbing to another one (for example from game to ff on the same monitor) stops the flickering but shift alt tabbing back the app is still flickering. When I drag app to different monitor it stops or sometimes starts again.

this has been happening for months now. I think I’ve had this issue since moving to wayland on kde plasma 6. I have an AMD GPU (5700XT) with both AMD-PRO and regular ones, so I can’t imagine it’s gpu drivers. I read somewhere that it might be VRR, but I’m not sure how to test that, turning off v-sync in games doesn’t help.

I think it also might be happening more likely when I stress my GPU (Coding in konsole/nvim is usually fine, but games start this issue, FF and discord sometimes). Pressing meta key to bring up menu bar sometimes stops the game from flickering but clicking back breaks it again, sometimes makes it worse.

Here are some example videos I recorded in slowmo:
https://workdrive.zohopublic.eu/folder/ewjjo23c9364e1ea6414ba7581e153dd609ac

  • There’s a slowmo without flicker (I can’t see it)
  • Slowmo with very bad flicker,
  • Slowmo where I see flicker, press meta and open menu, where I stop perceiving flicker(tho there seems to still be some)

On the very bad one, I see that it introduces ghosting, as if it’s switching between one random frame in the past and next one, as if video buffers get corrupted during switching.

On apps like firefox and discord it’s hard to tell if it’s ghosting, but it’s definitely flickering. Sometimes flickers like 3 times and stops, sometimes periodic, very random.

What could I do to fix this?

Try X11 from login page, bottom left.

Reboot

?

  • X11s screen tearing or compositor input lag aren’t far from flickering, rather have no screen tearing. Also, I use HDR
  • This has been an issue for months, restarting now won’t change much.
  • Houdini FX service, no clue what’s wrong with it, doesn’ŧ work anyways.

You might want to upgrade your bios to see if that helps

Maybe under System Settings > Display and Monitor?

Try to see if you have the same issues when only one monitor is connected.

Have you tried disabling HDR?

Maybe because the license server isn’t running?

The temperatures are borderline, heavy load or a reading error?

Be careful with this:

Oh my god how badly have I been taking care of my pc… I haven’t noticed the nvme being full nor GPU temps!

Thanks for pointing those out.

I just recently upgraded my 1440p + 1080p dual monitor setup to 4k 144hz HDR + 1440p, and never considered taking a look at how the GPU is doing. The default fan curve never went above 80% fan speed, so I set it more aggressively and now it doesn’t go above 80DegC, 100 DegC Mem.


Junkcture stays at 100DegC on max load, but that should be fine I think?

This flickering issue has been happening for months, and I got the new monitor this week. Maybe it was the high temps though, but that will take a bit of time to test.

I plan on doing maintenance, probably a clean ISO install, so I’ll see if disk space and GPU temps were to blame.

@TilliDie There’s been 2 bios updates since I last updated, thanks for the reminder, will do that.

I have checked and counted 8 BIOS/UEFI updates since your version :slight_smile:

The temps are much better now, if those are full usage (for example in a game), it is OKish. If these are in idle, then the temps are bad.

It looks to me like it’s a VRR problem with the monitor (I have the same issue on mine) when the frame rate goes below a certain threshold the monitor starts flikering, (the brigtness goes up slightly at lower fps) you can disable VRR in the system settings:

  • open the “System Settings” app
  • serch for “Display Configuration”
  • look for “Adaptive sync” and set it to “Never”

You might want so set it off on every monitor that has adaptive sync capabilities, this way you lose VRR but I think it’s way better than having the screen flickering all the time.

I did some more digging on the issue and found a way that works in my case, you might want to check it out.

Try to disable VRR in KDE Display Configuration. If its disabled and flickering is gone you know the reason. VRR currently in KDE should be always set to automatic and not always. This will turn on VRR only for full screen applications/games.

If you want to have VRR disabled per program or game while retaining the Adaptive sync automatic, you can create Widow rule.

There are links, AMD may have specific problems with ATOMIC modsettings.

i had flickering on ssd reading so enabled adaptive sync its ended but all started after last update.
