This is much harder to reproduce in Plasma 5.21 (
This is much harder to reproduce in Plasma 5.21 (Wayland in general seems much more stable), but if I drag a panel violently enough, it will still crash.
*** Bug 432061 has been marked as a duplicate of this bug. ***
I can confirm this. In fact, according to my testing, it doesn't even require switching screens. I managed to reproduce this simply by quickly moving between two sides of a screen fast enough. Moreover the backtrace (last thread) seems identical to the backtrace I got in https://bugs.kde.org/show_bug.cgi?id=433293 so perhaps it's the same underlying issue?

Sorry, please ignore my comment about the backtrace in bug 433293 being the same. I was under the wrong assumption that the crashed thread was the last shown by the debugger, but I got this clarified to me over #kde-bugs.
I cannot reproduce this issue in the Plasma Wayland session in current git master. Any chance you could check again wit unstable KDE packages from your distro, or in the Plasma 5.22 bets once it's released in a week?

Apologies, I didn't get a chance to test the 5.22 beta on real hardware. I can repro a crash in 5.22.0 when dragging panels, though overall Wayland seems more stable: Jun 10 01:07:48 fedora plasmashell[4486]: xdg_surface@567: error -1: invalid window geometry size (0x1080) Jun 10 01:07:48 fedora plasmashell[4486]: The Wayland connection experienced a fatal error: Protocol error Jun 10 01:07:48 fedora plasmashell[4770]: klauncher: Exiting on signal 15 Jun 10 01:07:48 fedora systemd[3155]: plasma-plasmashell.service: Main process exited, code=exited, status=1/FAILURE I'm not seeing a stack trace this time in journalctl but would be happy to supply more information.
Disregard me - I somehow updated only some components to 5.22.0. Everything looks good.
Experiencing this bug on KDE Plasma 5.23.0 on Arch Linux. Dragging a panel to any other display on Wayland causes plasmashell to hang.
