@RationalFragile I used controls like this before with no issues. Can you also provide a repro so it's easier to check if there are no other problems?

Doesn't ClipToBounds property fix it now?

Probably [box-sizing](https://developer.mozilla.org/en-US/docs/Web/CSS/box-sizing) from CSS solves similar problem in web. And not sure about UWP, but I think it's configurable there with [BackgroundSizing](https://docs.microsoft.com/en-us/uwp/api/windows.ui.xaml.controls.backgroundsizing?view=winrt-20348). Can somebody say, who are familiar with them,...

Does it work well with stable VS and Rider? If anybody have used it already.

It's 2021, shouldn't ResXFileCodeGenerator be replaced with new source generator?

YES! I definetly agree this is option is a must have.

If you have a simple stable repro, please provide one. It will help solving the problem.

Internally we agreed on ThemeVariant property name as for this moment. Might be changed depending on ControlTheme PR status. We want to avoid naming conflicts. ThemeControl should also be renamed...
