Description Tronje Krabbe 2020-03-20 15:01:29 UTC 
Application: kwin_x11 (5.18.3)

Qt Version: 5.14.1
Frameworks Version: 5.68.0
Operating System: Linux 5.5.10-arch1-1 x86_64
Windowing system: X11
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:

Firefox was focused. Other than that I don't remember doing anything special. I've been having ominous crashes every now and again, and I *feel* like this particular crash may be related to Firefox in some way, since this particular crash caused Plasma to restart and actually keep all applications open. I believe such a crash has occured before, and Firefox was open then, as well. But I don't remember this accurately enough to be sure.
The other crashes I've been experiencing have caused my system to freeze unrecoverably, so I think those are probably caused by something else.
Many thanks in advance for looking at this!

The crash can be reproduced sometimes.

-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault

I'll be happy to if you tell me how!
Comment 3 Vlad Zahorodnii 2020-03-26 10:12:38 UTC 
$ asp export kwin
$ cd kwin
$ vim PKGBUILD # add -DCMAKE_BUILD_TYPE=RelWithDebInfo to the cmake command
$ makepkg -i

After you've submitted a new backtrace install extra/kwin.

> Changing the status of the bug report to NEEDSINFO BACKTRACE.

Hi -- sorry, I meant to come back to this ticket earlier and close it, actually. I've been having copious amounts of issues with other software, and whole-system freezes about every hour. I'm fairly sure that this is a hardware issue at this point, and I'm definitely sure that KDE otherwise works perfectly fine. I do apologize for not getting back to this ticket earlier. I guess "NOT A BUG" matches the situation the best, so I'll change the status to that.
