We have found the issue and the problem will be fixed in the next update of the TMS VCL UI Pack.

If possible send us the fixed unit so we can test it in our application and speed-up the deploy of the new release of our application.

Hi to all,
we continue to see a wrong behaviour if in the project is set:
Manifest->Options->DPI Awarness = Per Monitor V2

The components TAdvSmoothPopup seem to work right if we set
Manifest->Options->DPI Awarness = GDI Scaling
But with this set in our application appear other problem on TAdvSmoothDock component, when the scale is different to 100% the TAdvSmoothDock don't work as expected, don't capture mouse movement and mouse click.

Please tell us what must do the Project settings and verifiy all TAdvSmooth component set.


We are currently working to fine-tune the fix to make sure that it works with Per Monitor V2 on Delphi 11.
We'll send another update when we were able to pinpoint the problem and solved it.

did you have some news about this issue?

We further worked on it and will send an incremental source update.

We do some more test and this is the results, pay attention that also components displayed inside the popup panels aren't scaled as expected.
We do the test with the last TMS VCL UI Package ver.
