Bug ID: 480092 Summary: Task Switcher with Thumbnail Grid / preview crashes Kwin when compositor is turned off Classification: Plasma Product: kwin Version: 5.90.0 Platform: Arch Linux OS: Linux Status: REPORTED Keywords: qt6 Severity: crash Priority: NOR Component: effects-window-management Assignee: kwin-bugs-n...@kde.org Reporter: tro...@troplo.com Target Milestone: --- Flags: X11+, NVIDIA+ Created attachment 165072 --> https://bugs.kde.org/attachment.cgi?id=165072&action=edit Crash log of kwin_x11 SUMMARY When disabling the compositor with CTRL + SHIFT + F12, the task switcher is expected to fallback to icon-only mode as it did in Plasma 5, instead it must attempt to render the thumbnails which are unavailable with the compositor disabled causing the entire shell to crash and restart with the compositor re-enabled. I've been using Large Icons instead as my primary task switcher to circumvent this issue. NVIDIA 545.29.06 on X11, Plasma 6 RC1 (Arch Linux) STEPS TO REPRODUCE 1. Enable Thumbnail Grid or another switcher which shows thumbnails 2. Disable compositor 3. Watch the entire shell crash OBSERVED RESULT The shell crashes EXPECTED RESULT The switcher falls back to application icons instead of attempting to render preview SOFTWARE/OS VERSIONS Linux/KDE Plasma: 6.7.0-zen3-1-zen KDE Plasma Version: 5.92.0 KDE Frameworks Version: 5.248.0 Qt Version: 6.7.0 ADDITIONAL INFORMATION Crash log attached.
