Platform: .NET 5.0

Environment: Windows 10 (64-bit)

Hi,

we are currently upgrading from version 19.1.687 to 21.1.3 and I have noticed that resizing the application is considerbly slower. I used the profiler to dig a little deeper and found out that the problem only occurs with visible WindowsFormHost instances.

    0,00 %   10 functions hidden  •  0 ms total
  0,16 %   OnRender  •  8 ms  •  System.Windows.Controls.TextBlock.OnRender(DrawingContext)

Do you have any idea how we can fix that?

Hi Tobias,

I believe in v20.1 or so we updated the ToolWindow and DocumentWindow controls to have a Transparent background. While this is fine for WPF controls, we found it did cause a performance decrease in WindowsFormsHost that has a Transparent background. You can see in the stack that GetBitmapForTransparentWindowsFormsHost takes up most of the time.

This documentation topic covers the issue in detail and tells you how to improve performance again like before:
