Windows flickering rapidly

Hi everyone,

I’m experiencing an issue where my windows flicker rapidly to black (multiple times per second). It’s inconsistent but occurs at least once an hour, and it’s quite straining on the eyes.

I notice it most frequently when scrolling long pages or switching workspaces. It affects Firefox, DBeaver, and Slack.

It seems tied to redraw events (scrolling) or compositor transitions (workspace switching).

What could be the issue, and how do I debug this?

System Environment:

  • OS: Fedora Linux 43.20260216.0 (Silverblue)
  • GNOME Version: GNOME Shell 49.4
  • Display Server: Wayland
  • GPU: AMD Radeon 890M
  • Firefox Version: 147.0.3 (64-bit), running in Wayland mode
  • Monitor Setup: External display only, 3840x2160, 60hz, Scale 125%

we had similar issues in this thread with intel arc GPUs. Severe display glitches on Fedora 43, Intel ARC B580 - #8 by lfav2012

maybe you could try the GSK_RENDERER tweaks in the config files that was proposed in this post Severe display glitches on Fedora 43, Intel ARC B580 - #15 by anotheruser it worked for me :thinking:

try GSK_RENDERER=gl (ngl has been renamed to gl and replaced the old gl renderer)
