Bug#794341: kwin-x11: Window manager often frezes when some of window is resized
Package: kwin-x11
Version: 4:5.4.2-1+b1
Followup-For: Bug #794341
Dear Maintainer,
For me the bug is on startup: kwin freezes and the only way to use it is to go
in console (ctrl + alt + f1) and use DISPLAY=:0 nohup kwin --replace & (I use nohup
so I can free the tty) or by kill -9 kwin and kwin.
Attached is a kcrash generated file occurred once, if it
can be useful. I think more info could be found in .xsession-errors, if you think
it could be useful I'll attach it.
