ADDITIONAL INFORMATION

Fedora 41 desktop. Gnome on Wayland works fine.
This bug manifests only on plasma desktop.

Comment 2 Nate Graham 2025-03-07 19:59:54 UTC

What kind of GPU does the system use?

Can you take a phone photo of what the screen looks like when the system is in this state?

lspci | grep -i vga
06:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Cedar [Radeon HD 5000/6000/7350/8350 Series]

glxinfo | grep -i "OpenGL renderer"
OpenGL renderer string: AMD CEDAR (DRM 2.50.0 / 6.13.7-200.fc41.x86_64, LLVM 19.1.7)

Bug still manifests but infrequently. I will try to provide snapshoot.

plasmashell --version
plasmashell 6.3.3
QThreadStorage: Thread 0x55bafc15d970 exited after QThreadStorage 8 destroyed
QThreadStorage: Thread 0x55bafc15d970 exited after QThreadStorage 3 destroyed
QThreadStorage: Thread 0x55bafc15d970 exited after QThreadStorage 2 destroyed

So far, so good.
No display corruption.
If display is corrupted, it looks like no horizontal stroke synchronization.

No luck. See corrupted display.

Thanks. This is a classic GPU driver issue. Since you're using an AMD GPU, you can submit a bug report for the Mesa project, which is where the AMD drivers live: https://docs.mesa3d.org/bugs.html
