Created attachment 186832 [details] Log SUMMARY Sometimes (mostly when I get my PC into sleep for a night) kwin_wayland crashes. I have no stable repro, but its really annoying since I lost everything I opened before. STEPS TO REPRODUCE 1. Put PC to sleep 2. Wait 3. Resume from sleep OBSERVED RESULT kwin_wayland crashes, Xwayland applications (Steam, for example) lose native scaling. EXPECTED RESULT kwin_wayland doesn't crash SOFTWARE/OS VERSIONS Operating System: Fedora Linux 43 KDE Plasma Version: 6.5.2 KDE Frameworks Version: 6.19.0 Qt Version: 6.10.0 Kernel Version: 6.17.7-300.fc43.x86_64 (64-bit) Graphics Platform: Wayland Processors: 12 × AMD Ryzen 5 7600 6-Core Processor Memory: 32 GiB of RAM (30.9 GiB usable) Graphics Processor: AMD Radeon RX 9070 XT ADDITIONAL INFORMATION I use KDE since F42 and never see anything like this before. I don't really remember when its start happening. Some other info Mesa: user@fedora ~> glxinfo -B | grep Mesa OpenGL core profile version string: 4.6 (Core Profile) Mesa 25.2.7 OpenGL version string: 4.6 (Compatibility Profile) Mesa 25.2.7 OpenGL ES profile version string: OpenGL ES 3.2 Mesa 25.2.7 I undervolted my CPU (Ryzen 7600) and I started get this more often? But I also update my KDE to latest version, so I don't see any connections to this crashes. Games are stable and prime95 doesn't generate any errors or unstable behavior. I attached logs from crash

I get this issue almost always when I put my PC to sleep for a long time. If I can provide any kind of information for help fix this - let me know.
I reset my BIOS completely - and have this issue anyway. So this culprit is - new 6.17 kernel from f43, new Mesa or KDE itself.
Not an issue on kwin_x11, so I don't know. Everything works fine except kwin_wayland.
