SUMMARY Sometimes, when I press the Super key to open the start menu, Plasma crashes. I still see all my windows, but the Panel, my desktop background + widgets turn black, with Plasma apparently restarting after roughly 2-3 seconds (widgets take a bit longer than that). SOFTWARE/OS VERSIONS Linux/KDE Plasma: 6.14.0-37-generic KDE Plasma Version: 6.5.4 KDE Frameworks Version: 6.21.0 Qt Version: 6.10.1 On KDE Neon with Wayland ADDITIONAL INFORMATION `journalctl /usr/bin/plasmashell` of the relevant section: ```plain Dec 30 20:36:05 pctorge plasmashell[51281]: xdg_surface#259: error 3: attached a buffer before configure event Dec 30 20:36:05 pctorge plasmashell[51281]: The Wayland connection experienced a fatal error: Protocol error Dec 30 20:36:06 pctorge plasmashell[52154]: QWaylandGLContext: Failed to create the decorations EGLContext.

The issue appears to be gone after a reboot.
Thanks for the bug report. It looks like Plasma runs into a Wayland protocol error, not actually a crash: Dec 30 20:36:05 pctorge plasmashell[51281]: xdg_surface#259: error 3: attached a buffer before configure event Dec 30 20:36:05 pctorge plasmashell[51281]: The Wayland connection experienced a fatal error: Protocol error We had tracked this in bug 486449 and thought it was fixed with an update to Frameworks, but you're running a current version of Frameworks. At this point, we need to figure out which exact thing is causing this on your system. Can you please run `WAYLAND_DEBUG=1 plasmashell --replace` in a terminal window, then reproduce the crash, and then attach the entire contents of the output (it will be long) as a file here? I realize it may take time, and perhaps multiple attempts. Thanks!

Thanks for the logs. The plasma developers will take a closer look.
There's also Bug 506412. Looks like it was never fully fixed. :/
