*** Bug 498319 has been marked as a duplicate of this bug. *** *** Bug 498776 has been marked as a duplicate of this bug. *** A possibly relevant merge request was started @ https://invent.kde.org/plasma/kwin/-/merge_requests/7031 Git commit c79ef9055f3b6717d0660998c1997dac9199eabb by Xaver Hugl. Committed on 17/01/2025 at 14:22. Pushed by zamundaaa into branch 'master'. backends/drm: asynchronously wait for idle before doing modesets The previous code relied on waitIdle() *always* working, which isn't the case. Sometimes, weird kernel bugs can make the timeout trigger wrongly, and sometimes, the kernel just doesn't send a pageflip event in a reasonable time frame or at all.

Application: kwin_wayland (6.2.4) ApplicationNotResponding [ANR]: false Qt Version: 6.8.0 Frameworks Version: 6.8.0 Operating System: Linux 6.11.10-300.fc41.x86_64 x86_64 Windowing System: Wayland Distribution: "Fedora Linux 41 (KDE Plasma)" DrKonqi: 6.2.4 [CoredumpBackend] -- Information about the crash: I activated standby mode recently. After I came back and turned my system on again I only saw a black screen for around 10 seconds. My monitor reported "No Signal" during the black screen. After that I saw my login screen again. After I logged in I saw the crash notification for KWin. The crash can be reproduced sometimes. -- Backtrace: Application: KWin (kwin_wayland), signal: Segmentation fault Content of s_kcrashErrorMessage: std::unique_ptr<char []> = {get() = <optimized out>} Downloading separate debug info for /usr/bin/kwin_wayland...
