I have experienced similar result on octave on cygwin and octave on wsl (ubuntu 
18.04).

In my case, issue was solved by changing Xserver option.

The qt graphics_tookit strongly depends on hardware and software setting of 
graphics. 

I cannot give you solution for your case.  
I advise you to write more details of hardware and software information for 
graphics.
