Fatih Demirdag created a new topic ' TForm Paint Speed in 10.2 vs 10.1 (Android)' in the forum. 6 years ago

I'm programming a game and recently switched to Delphi 10.2. FPS dropped. After searching for some time I think it is becasue of TForm paint speed.
Here is my test:
1 Created a new Multi-Device application.
2 Put a TTimer on it.
3 Timer interval set to 1
4 Timer OnTimer event calls Form.Invalidate
5 Deploy on an Android Device (Samsung Note 10.1 2014 Edition)
6 Open Intel GPA System Analyzer and run the application.
If these steps are done using Delphi 10.2 CPU usage and GPU calls are seems normal but FPS is capped 48-50.
if these steps are done using Delphi 10.1 FPS is 230-240
(I also checked Timer speed without invalidate it seems to run @~1000Hz so timer is not the problem)

So why is that? Is this a bug?
