Bug 442526

Application: kate (20.12.3)

Qt Version: 5.15.2
Frameworks Version: 5.80.0
Operating System: Linux 5.11.0-35-generic x86_64
Windowing System: X11
Drkonqi Version: 5.21.4
Distribution: Ubuntu 21.04

-- Information about the crash:
- What I was doing when the application crashed:
I was just about to change the color of the highlighted brackets. I clicked on the "custom" color choice and then i chrashed.
Prior to that fatal move I was tinkering with Kvantum Manager and Systemsettings5. I had just experimented with making every window, dropdown menu, Dialogs, slightly transparent.
Open apps at the time where Synaptic Package Manager, Kate, Systemsettings5, Google Chrome Beta.

- Custom settings of the application:
Nothing special, I was just seting upp all the buttons in the UI the way I want.

I have been playing around alot with themes, colors and graphics settings all day though and this was my sixth (I think) crash for today so there's something not quite right.
Unfortunately everytime I'm trying to complete theese crash reports I get another crash which have been fatal every time. I do have one report saved though but I don't know if its
possible to complete a report once the computer has been rebooted. I'm gonna look into that after this.
The crashreports are mostly jibberish to me but I have noticed that every time I have a crash Qt5 is ALWAYS mentioned.

Hmm, what else could be important...
I'm trying to get KDE, Qt5ct GTK and Kvantum to play nice with eachother so alot of tinkering with all their settings.
I'm using OpenGl 3.1 and have Plasma Renderer setup to use Open GL and not software, and also the threaded option.

I have three monitors, two on a Nvidia card and the third runs on an integrated intel card.

Anything else you need to know just send an email I always answer. Good luck

The reporter is unsure if this crash is reproducible.
