ADDITIONAL INFORMATION

Comment 1 Patrick Silva 2019-10-17 12:21:21 UTC

I can confirm on my system.
Wayland session also crashes when...

I enable the OSD that appears when we switch between virtual desktops in virtual desktop KCM

I change the Global theme

I change the window decoration

I change any font setting

I change the task switcher (I changed from default theme to Large Icons)

Reported as bug 411980 before Plasma 5.17 to be released.

Any crash needs a backtrace, otherwise we can't do much.

(also sorry for not replying to you Patrick earlier)

Comment 3 Vlad Zahorodnii 2019-10-31 11:38:10 UTC

That's most likely one of dmabuf crashes.

Comment 4 Patrick Silva 2019-10-31 14:27:52 UTC

yes, I can't reproduce this crash after update to kwin 5.17.2.
