Error creating scaled form with TRibbon.

[HAiDA]

I have an editor based on the ActionTestRibbon demo, and if the magnification in Windows is set to 125%, I get an error when creating the form with Ribbon. The demo ActionTestRibbon is behaving correctly, but I can't figure out why my form isn't working at all. It works properly at 100% magnification. Testing on Delphi 10.4.1. Does anyone have more experience with Ribbon? Thank you.

In fact, the demo also doesn't work. When I set DPI Awareness to Per Monitor v2, an error also occurs when creating the form. I assume that this is again a TRibbon error

I am afraid TRibbon supports only 96 dpi.
I suggest searching for a third-party alternative.

This would explain the rendering errors.
