I tried to re install windows and visual studio, but I couldn't fix the problem. Later it was found that the problem was the driver of AMD graphics card. When I unloaded the graphics driver, the XAML design interface displayed normally. I will have problems installing any version or the latest version of the graphics driver. I've already fed this back to AMD.
WPF design interface display is not normal
I have updated to the latest version of visual studio Community Edition（2019 v16.7.5）.
But WPF design interface display is not normal. The form background has a black square, and the properties window becomes black. Changing the visual studio theme can temporarily solve the problem, but once the software is restarted, this will happen again.

Besides, it seems that this issue is related to AMD graphics and I noticed that you have fed this back to AMD.
