Unfortunately the backtrace lacks debug symbols. Please install kwin debug packages and submit a new backtrace.

Hmm, installed kwin debug packages together with latest kernel (5.0.6-200). Now I do not get any kwin crash; not even when I provoke it. Had this kwin crash all the way from F28.
Comment 3 Vlad Zahorodnii 2019-04-15 23:19:35 UTC
Hmm, that's really bad. Could you please post output of `qdbus org.kde.KWin /KWin supportInformation`?

Comment 7 Vlad Zahorodnii 2019-05-20 07:53:36 UTC
Hmm, the new backtrace is unrelated to the first one.

In the first one, the crash happens in the main thread. Most likely when the background contrast effects runs.

In the new backtrace, the crash happens in the video driver (in a qt quick render thread).

ps. I hate Bug Janitor Service.
Comment 8 Vlad Zahorodnii 2019-05-20 07:54:06 UTC
Resetting the status back to needsinfo.
