Commen= t # 4 on bug 11123= 4 from jamesp= harvey20@gmail.com 
Just ran into this for my first time.  I've had pretty consist=
ent problems with
the potentially related bug that Nicholas Kazlauskas mentioned at
https://bu=
gzilla.kernel.org/show_bug.cgi?id=3D204181

Could certainly be the same bug, but definitely has a different backtrace.

Also running KDE, also running multi (5) monitor.

Was on linux 5.2.10, mesa 19.1.6, plasma 5.16.4.
