Bug ID: 428951
Summary: kwin crash avery time I open a window
Product: kwin
Version: 5.17.5
Platform: Debian stable
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: piv...@riminilug.it
Target Milestone: ---
Application: kwin_x11 (5.17.5)
Qt Version: 5.15.1
Frameworks Version: 5.74.0
Operating System: Linux 5.9.0-1-amd64 x86_64
Distribution: Debian GNU/Linux bullseye/sid
-- Information about the crash:
Hi all, after the login in a kde session I get an unusual long time before
seeing my desktop. Furthermore if I open a program I can see that kwin crashes
and I don't have window decoration, no windows buttons at all and the program
is not shown in task bar so all the system is unusefull. Perhaps depend on the
upgrade of the libkf5screen7?
If you need more infos I'm here.
Piviul
The crash can be reproduced every time.
-- Backtrace:
