Description Patrick Silva 2018-02-16 16:52:57 UTC

I'm using plasma 5.12.1 + QT 5.10.1 on Arch Linux.
Every time I right-click a window decoration, Wayland session crashes and my system goes to login screen. Or I get a black screen without cursor and I need to force my computer to restart.

We need a backtrace, without we cannot do much.

Comment 2 Patrick Silva 2018-02-16 20:02:23 UTC

I also cannot do much. There are no debug packages in Arch repositories, I dont know another distro already running qt 5.10.1, there is no guide to generate backtrace when whole session crashes.
Maybe another user affected by this crash can provide a backtrace.

alt+tab also crashes Wayland session.
Well, qt 5.10.1 makes Wayland unusable.
