Bug ID: 460446
Summary: kwin_x11 crashes as long as the window of a specific
xcb/vulkan app exists.
Classification: I don't know
Product: kde
Version: unspecified
Platform: Archlinux
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: general
Assignee: unassigned-b...@kde.org
Reporter: k...@hurrikhan.eu
Target Milestone: ---
SUMMARY
kwin_x11 5.26.0 crashes with an xcb application. It seems the issue is recent.
It happens around when the window is exposed. As long as that window exist,
kwin_x11 keeps crashing in a loop.
The window is created by a test program of mine.
There are two stacktraces. One for the initial crash, one for every following
crash until I kill the "bad" window.
Here is that one's backtrace:

STEPS TO REPRODUCE
Hard to say, beside this serie of events. But I've pasted the code that seems
to be the cause below.
OBSERVED RESULT
Crash loop. Rarely : no crash until a second or two has elapsed (and during
that time the program is drawn as intended)
EXPECTED RESULT
Not crashing.

I'm on Artix, update of today. (I've not touchrf the code crashing kwin_x11 for

ADDITIONAL INFORMATION
The program that crashes kwin_x11 opens an xcb window in order to do some
Vulkan rendering (the Vulkan library isn't even loaded at the time of the crash
though)
The thread creating and setting-up the window is separate from the one handling
the event loop.
As long as the window of the program exists (paused in its debugger) kwin_x11
will crash in a loop. I presume something in its setup/state is the cause.
After the first crash, the stacktrace becomes:

Here, if I look at the instruction that triggers the crash, it's :

The event loop is pretty minor and mostly dump the events and frees the memory.
Finally, I've kept the output of /usr/bin/kwin_x11 --replace and crashed it
immediately:
