Description alek.sandar0 2018-06-22 17:14:16 UTC

Application: kwin_x11 (5.13.1)

Qt Version: 5.11.1
Frameworks Version: 5.47.0
Operating System: Linux 4.17.2-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
Running a video game called StepMania which was compiled from source. Since the compositor didn't turn off when I ran the game, I manually set the special application setting to block the compositor. Restarted the game from Konsole and everything worked at the end, the window decoration was there, everything was intact, except I got the message that KWin crashed.
I was not able to reproduce the same crash.

- Unusual behavior I noticed:
After setting up the special application settings the desktop briefly showed Falkon web browser from the other workspace. But what is very noticable is a black square in the upper left corner when the compositor is turned off. I though it was the icon for the application launcher, but it stayed there when I moved the taskbar. This black square sometimes happens in other games, such as Dota 2. This sometimes happens when disabling the compositor.
I've also noticed that I can't bring up application dashboard with super key. Pressing the panel's application dashboard icon was switching to other workspace and bringing up Discord. After closing down Discord the button was working as intended, but the super key was not working.
After some time and relanching the game a couple of times the black square wasn't happening anymore, the panel icon for dashboard was working and the super key was not working.

- Custom settings of the application:
The application setting I did change is the blocking of the compositor when the program launches.
Window decoration that I used is called "WindowsK10", and the desktop theme is "Breeze Transparent Dark"
It's probably worth mentioning that I'm also using Latte Dock and running Arch Linux.

Honestly, it would be best for this to be closed. I've not experienced any crash as of writing this report. Perhaps it was fixed or maybe it was some wild configuration I had running. I am unable to reproduce this bug.
