Tadvsmoothpanel opacity problem

Hello since a long time i was using Tadvsmoothpanel because i want to have a panel bu t i want see what is behind , it was working fine , now on developping mode the panel is transparent but when i start the progran it is not.
here a sample of before and after

first image in dev mode transparent false then true then in exe mode

I am using Delphi 11 and Tadvsmoothpanel

Transparency is for the rounded corner areas. I do not see you use rounded corners here?

Hello Bruno , i don't understand rounded corner areas , i made a test with a form with a labet and when i put the same Tadvsmoothpanel , it's OK

I retested this here and I could not reproduce a problem

If a problem persists, please isolate this and send a sample source app with which we can reproduce this issue here.

Hello Bruno ,
i know how to reproduce the problem , if you create a form with code it's not ok if you create with the project it's ok
the sample here
thanks DAVID

I retested this here on two different machines with 2 different IDEs but I could not see any problem.
I see the semi transparent TAdvSmoothPanel on both forms:

Here the video of the test on my computer

As I cannot see this issue on multiple machines, can you try this on another machine?
