SUMMARY Whenever I play something with Jellyfin and enter fullscreen, the screen freezes. Pressing keys and audio still work, but the screen is completely frozen. It only happens if I use Wayland and Fractional scaling. It doesn't happen with Gnome or X11. Using kernel 6.11.4 and Mesa 24.2.8 doesn't help. ``` Mar 18 01:00:43 thinkpad kwin_wayland[4525]: kwin_scene_opengl: 0x1: Shader Stats: SGPRS: 48 VGPRS: 12 Code Size: 1100 LDS: 0 Scratch: 0 Max Waves: 10 Spilled SGPRs: 0 Spilled VGPRs: 0 PrivMem VGPRs: 0 LSOutputs: 0 HSOutputs: 0 HSPatchOuts: 0 ESOutputs: 0 GSOutputs: 0 VSOutputs: 0 PSOutputs: 1 InlineUniforms: 4 DivergentLoop: 0 (PS, W64) Mar 18 01:00:44 thinkpad kernel: amdgpu 0000:06:00.0: [drm] Mode Validation Warning: Unknown Status failed validation.

The log you pasted says what this is, and what you can do about it (once gitlab.freedesktop.org is up again). There's no bug in KWin here.
(not meant to be rude, but a genuine question) How did you decide to report it here, rather than reporting it to amdgpu? What can we do to make it more obvious that it shouldn't be reported to KWin? The three big graphics vendors have a lot of these kinds of issues, so we get a lot of bug reports about it. The existing logging was added to make as many people as possible report it directly to their graphics vendor with at least some useful information, instead of our bug tracker filling up with driver issues. If you could help make it more effective, that would be very useful. Thanks!

Thanks! The messaging is already very clear, I just thought of reporting it here since it happened in a very specific way only with Plasma. And you aren't rude at all. I will report it to amd's bug tracker whenever it's back up (the 22nd i think?). And you aren't being rude, don't worry about it.
