Describe the bug
On my fullscreen app, there are clear rendering artifacts when using Direct2D on a display with a scaling factor above 100%. See the following videos for demonstration:

Skia:

The animation is quite simple. It's just a ScaleTransform on a Grid with a TransformOperationsTransition. With Direct2D, it appears to have some weird overlapping rendering issues of some sort.
Even with the animation removed, there is still an artifact where the content gets partially cut off on the left side:

Also note that ClipToBounds does not work properly with Direct2D, as seen on video with the Content border.
To Reproduce
- Download this project: BrokenDirect2DScaling.zip
- Set display scale in windows to 125% or beyond (Tested on 1920x1080 display)
- Open solution and run Direct2D configuration
Expected behavior
Content renders properly
Avalonia version
11.2.4
OS
Windows
Additional context
The AngleEgl rendering mode results in a blank window, therefore Vulkan or Software is used instead. Both Software and Vulkan result in the same rendering artifacts.
Using Skia is not really an option for me unfortunately, as there is noticeably more lag when using software rendering which is a common setup for my use case (pre-driver environment).
