Description Simao Gomes Viana 2018-03-28 21:23:58 UTC

Application: kwin_x11 (5.12.3)

Qt Version: 5.10.1
Frameworks Version: 5.44.0
Operating System: Linux 4.15.13-1-ARCH x86_64
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:
I was using IntelliJ, there was a window which I just closed by clicking on Cancel and was about to click on "File" at the top.

- Unusual behavior I noticed:
Just before I clicked on "File" the screen flashed very quickly (showed just the wallpaper for like 0.2 seconds) and then KWin crashed, basically getting rid of all window decorations etc. for a few seconds.

- Additional information
I'm using a NVIDIA GeForce GTX 660 with proprietary drivers (nvidia package installed from Arch repos) since the OSS driver nouveau isn't working properly (and tbh the proprietary one isn't really better either, just does not have issues I can't deal with)

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

Crash happens in the proprietary Nvidia driver. Please report to NVIDIA.

Alright then, I figured this would happen.
I'm going to report this to NVIDIA as suggested, thanks.
