Qt Version: 5.13.2

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

I was trying to set my screen resolution to 1920x1080
I test this.
xrandr --newmode "1920x1080"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync
xrandr --addmode default 1920x1080
xrandr --output default --mode 1920x1080 --gamma 1:1:1
xrandr: screen cannot be larger than 1024x768 (desired size 1920x1080)

so I went into the graphical screen parameter .
I saw that the new mode 1920x1080 was avalaible and try to apply it.

Then I got an error message 

when I select the older setting 1024x768 the programm crashed

- Custom settings of the application:

trying new mode 1920x1080
