Diagnosis: It seems that the calculation of the vertical font size for the surrounding TextRect leads to wrong results if no font is specified and the system default is going to be used. In order to change that, I will hard code 'Arial' as the default if no specific font has been set.

1daffb2 should fix the problem. I will test it on Windows and then close the issue.

Hello @fartleako,
I have tested it under Windows 11 (the only Windows I have access to at the moment) and there has been no problems in display. See the picture below. I'll mark the topic as solved for now.
If any problems still arise, feel free to open it again.
