Issues with hdpi display under Windows 10

[daviddem]

Hello,

Pardon me if this has been addressed, I searched and did not find a proper solution. After installing FreeCAD for the first time ever on my Windows 10 laptop with hdpi display (3480 x 2160), the interface is messed up (splash screen, menus etc... nothing is in place - see below screenshot of one of the manipulator windows for example).



After searching and unsuccessfully playing with the compatibility options, I found that creating the environment variable QT_AUTO_SCREEN_SCALE_FACTOR and setting its value to 1 or 2 solves the problem. See below:



However, setting this environment variable messed up other programs that use Qt, such as Free Download Manager for example (and no, this window is not resizable):



So my question is: is there a better way to get FreeCAD to display properly on a hdpi monitor under WIndows 10?

First try: use FreeCAD 0.19, it has a new Qt library which hopefully fixes this. If this doesn't help: can you start FreeCAD from a script? Then you can set the environment variable individually for FreeCAD.

No problems here.

Indeed FreeCAD_0.19.19127_x64_LP_12.1.2_PY3QT5-WinVS2015 does not have the issue I described (and my other programs are also looking ok while FreeCAD 0.19 is running). Guess I should have tried that first before spending hours tinkering .

Thanks for making me aware of the development builds, I hadn't paid attention when I downloaded FreeCAD 0.18.

It's strange if the issue was resolved in 0.19 and reappeared in 0.20.2 that I'm using. I had to force the application to scale via Windows 11 application properties, which resulted in blurred text, which I prefer from tiny text (in the settings and dialog boxes).

Is this a known issue or is there a configuration setting for the application to adapt to HiDPI display (4K 27 inches, 150% scaling in Windows 11) ?
