Bug ID: 435941
Summary: Crash on sleep
Product: kwin
Version: git master
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: aleix...@kde.org
Target Milestone: ---
I left my system to go make dinner with both a running session on tty3 and a
valgrind debug session on tty4. Both of them crashed. I got slightly different
backtraces on both, boiling down to a crash when deleting a GLTexture:

It all seems to happen when my displays go to sleep

Note: see also the FAQ in the source distribution.
It contains workarounds to several common problems.
In particular, if Valgrind aborted or crashed after
identifying problems in your program, there's a good chance
that fixing those problems will prevent Valgrind aborting or
crashing, especially if it happened in m_mallocfree.c.
If that doesn't help, please report this bug to: www.valgrind.org
In the bug report, send all the above text, the valgrind
version, and what OS and version you are using. Thanks.
