I am getting the very same issue if WGL is enabled even for simpler apps on various Windows 10 and Windows 11 machines. ``` 2022-01-14 00:02:20.037 | Avalonia | TID[...

Please note that a simple Attribute like ```ValidatedNotNullAttribute``` would not fix the problem even if it worked because the custom assertion is able to check any kind of boolean construction.

I found one workaround which is very specific however: ```csharp Assert.NotNull(systems, "Text"); return systems.GetPose(coordinateKey.Value, Core.Geometry3D.CoordinateKey.World) * Pose; //... public class AssertionMethodAttribute : Attribute { } public sealed class ValidatedNotNullAttribute :...

We have finalized a Vulkan integration into WPF using DXGI similar to Microsofts sample implementation [WPFDXInterop](https://github.com/microsoft/WPFDXInterop). Hence, we integrated our Vulkan 3D renderer with DX11 and made interoperability work with...

Thanks for the feedback. ...and indeed the style I created uses corner radius. So any thoughts and how to work around that?

Thanks for this analysis. Would you recommend to set `RenderOptions.EdgeMode="Aliased"` ?

I don't believe we can tolerate Aliased. So, we could either do a workaround and try to invalidate the background panel once the slider changes (how would that be done?)...

> Could you try playing with `RequiresFullOpacityHandling` that creates a full layer for the sub tree For the slider or the parent panel?

Double checked: - `RequiresFullOpacityHandling` does not change the behavior. Neither for the surrounding panel nor for the slider - `RenderOptions.EdgeMode="Aliased"` prevents the problem but indeed the corner radius looks rougher

> @llfab Good to know, I think the only possible work-around with no visible downsides is a special clipping geometry. Good. Any kind of coding hints on how to do...
