Setting up in Percentage, it works fine, but if it has components inside, then all of them Resizes automatically. Hope this bug is for all components I think so as I have tested with arrangements, buttons,textboxes and all performs same.
Same way Height is set as Automatic, the size of the component looks bigger
I had solved this issue with tests to can put fix-variable dimensions as, for example, WidthComponentX=85%*ScreenWidth, only where I have the problem. The result is almost responsive.
