I finally upgraded from Delphi 10.3.3 and SkinEngine 14.37 to Delphi 10.4.2 and SkinEngine 15.23 and I’m seeing a problem with my button presses.

When I press a button I get a distinct flicker or flash of it in white before it gets repainted. The times vary and can be up to 0.1 seconds I estimate. The program (64-bits) works but it cannot be released like this. There was no flicker at all before.

As a test, I swapped out our skin for the “Cold” skin. The Cold skin has the same button flashing artifact as I saw with our own skin.

What can I try next? I’m stumped. Is there some new property somewhere I can adjust?

Thanks in advance, Rob Crandall

Hello, Rob!
Manifest is enabled in this project?
Such behavior is possible if application was built without manifest.

Thank you for the speedy reply! That gives me something to Google now.

I was doing some tests this morning and found that the behaviour changed from 15.13 to 15.14. Up to ver 15.13 there was no flicker, after 15.14 it flickers for me.

I will read up on manifests now!

Thanks again, Rob C

OK, checking “Enable Runtime Themes” seemed to fix the problem for me. Is this the correct answer? I ask only because I ended up poking things at random until something worked and that is not always the best way to go, lol.

Cheers, Rob C

If manifest is not used then old API used for drawing and some useful features are not available for application. The application works in mode of compatibility with Windows Vista if I’m not wrong. So, I recommend to use a default manifest there. And I will check buttons without manifest, maybe I will find a solution.
