Description Aleix Pol 2020-01-09 15:14:40 UTC
Application: kdevelop (5.4.40)
 (Compiled from sources)
Qt Version: 5.14.0
Frameworks Version: 5.66.0
Operating System: Linux 5.4.8-arch1-1 x86_64
Windowing system: Wayland
Distribution: "Arch Linux"

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

It doesn't really happen all the time, just quite often.  see from other bg repots that it's possibly something upstream but it's definitely a problem for KDevelop' usage.

The crash can be reproduced sometimes.

Comment 2 Aleix Pol 2020-01-09 16:08:47 UTC
Unsure, I'm in 5.14 branch. I could try reverting the commit mentioned on the bug...

I have no idea how to predictably reproduce it.
Comment 3 Aleix Pol 2020-01-17 23:13:35 UTC
The commit is already reverted in 5.14.
Also the test case from the bug report doesn't trigger on me.
Comment 4 Justin Zobel 2022-10-03 10:36:23 UTC
