Description Maxim Sheviakov 2017-06-24 09:27:36 UTC

Application: kwin_x11 (5.10.2)
 (Compiled from sources)
Qt Version: 5.9.0
Frameworks Version: 5.35.0
Operating System: Linux 4.11.6-1-ck x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
Maybe it is somehow related to KWin not handling something properly, because (as far as I have noticed) it happens after "de-minimizing" some window - any window, I think.

The crash can be reproduced sometimes.

-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".

As with all Arch bug reports the backtrace is unfortunately useless.

Do you mean with binary packages from Arch? If so, I build my Plasma from source... If it means something, of course.

Comment 3 Christoph Feck 2017-06-28 01:52:40 UTC

No need, the crash is in radeonsi_dri.so (the Radeon OpenGL drivers).
