Description Luis Cáceres 2020-08-01 01:51:44 UTC

Every time I try to start a Wayland session (whether through sddm or `dbus-run-session startplasma-wayland`) kwin_wayland crashes.

This did not happen in kde-plasma/kwin-5.19.3.

Reproducible: Always

gdb backtrace

I managed to obtain a gdb backtrace. Crash seems to happen inside libwayland.so from dev-libs/wayland-1.18.0, which hasn't had any updates in the last couple of months.

Next few frames are in libKWaylandServer.so.5 from kde-plasma/kwayland-server. I checked the source (https://invent.kde.org/plasma/kwayland-server/-/compare/v5.19.0...v5.19.4) and there hasn't been any changes since 5.19.3 so I'm unsure why it may suddenly start crashing now.

Try with dev-libs/plasma-wayland-protocols-1.1.1.

That fixed it. Thanks!
