I have a frustrating thing, in short; I have an application with lots of different users and thus different Windows installations ( 7-11 ). The problem with my app build with D11.2 is that I deployed it with: DPI Awareness - PER MONITOR V2'. Suddenly some customers are complaining that there where buttons totally 'off-screen'. I checked the system of a customer who had that problem and it was a 'new' laptop with Windows 11 installed and enough resolution for displaying everything. So it should not be a problem. When I set the DPI Awareness to NONE it worked.  But now are other customers complaining with same problem. It's sooooooooooo frustrating.  I expect/hoped from Embarcadero that if I don't use any external manifest file and just turn on PER MONITOR V2 on in the project settings. That my executable is running fine on a modern ( read Windows 11 ) system. While reading some articles I saw that @Uwe Raabe recommended that ParentFont 'must' be set to true. But in this article https://docwiki.embarcadero.com/RADStudio/Alexandria/en/High_DPI is stated that for the Form ParentFont must be set to false. A bit confusing.....!!!  ( docwiki seems to be down, use cache ). I see that in my app ParentFont are a bit mixed. I might be the problem..... So practical said; I am dropping (DevExpress) components on a form and I am running my applications ( yes I tried TForm and TdxForm). I also don't want to change the DPI awareness on runtime, but I am frustrated. For example now; my IDE (VCL Designer High DPI) is set to 96 DPI, this is not what I want but gives me the best results so far. Not good, but the best results.  ( When I look in my DFM's the PixelsPerInch  are 120 ). For example now I have the situation with the above settings that running my app (on a Windows 11 machine) with 192 DPI I get panels overlapped, see attachment. This is not the way I designed it. On running on Windows 11 machines with lower resolution it looks okay. So RUNTIME SCALING IS NOT GOOD! I have lots of forms and most of them are okay. And I don't see where to look/to fix this.
