Comment 1 David Edmundson 2019-01-23 01:21:56 UTC

3  QMessageLogger::fatal 

"Xwayland Connection died"

Please can you try to get a backtrace of xwayland and report to the X developers.

Comment 2 Patrick Silva 2019-01-23 21:37:15 UTC

Weird. coredumpctl command shows no crash related to Xwayland process.

Comment 3 Martin Flöser 2019-01-24 07:04:17 UTC

It's possible that it didn't crash but decided to exit.

Comment 4 Vlad Zahorodnii 2021-10-13 13:30:07 UTC

kwin handles xwayland dying. marking as RESOLVED WORKSFORME.
