I have developed an application what - for one user - shows a tiny font size:
The title bar is not affected by this strange behaviour.
The menustrip and the tab control however is.
I don't play with the font at all. I've tried different DPI settings in a sandbox, and for me, this effect never occured.
The user runs his monitor at 1920-1080 (recommended). He has an Hi DPI monitor.
DPI is at 100%.
No accessibility settings applied.
This reminds me of a situation I had with an Ultra-HD monitor, but I don't remember how I overcame the problem.
Does anybody have any idea?
Thank you very much!
