Description logicreasondoubt 2017-06-23 04:03:37 UTC

Application: plasmashell (5.10.2)

Qt Version: 5.9.0
Frameworks Version: 5.35.0
Operating System: Linux 4.8.0-56-generic x86_64
Distribution: KDE neon User Edition 5.10

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

It seems that Kwin will crash sometimes when starting a video game. It happens regularly when opening Rocket League or Hitman. I usually hit Alt + Spacebar to activate krunner and type kwin, then press enter to get everything working again. This is why I believe it may be kwin crashing.

- Unusual behavior I noticed:

When opening a game, all open windows will lose their titlebar & window controls. The windows seem frozen and immobile until I start kwin again.

- Custom settings of the application:

CPU is i5-4670K , Graphics card is MSI RX480 8GB, w/ 16GB of DDR3 Ram. Using the default drivers from the kernel.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault

Comment 1 Martin Flöser 2017-06-23 17:29:55 UTC

Backtrace is from Plasma, not KWin.

Comment 2 Christoph Feck 2017-06-29 00:09:18 UTC

Please do not mix multiple bug reports into a single ticket. If KWin crashes, report it with the kwin_x11 backtrace. If plasmashell crashes, report it with the plasmashell backtrace.
