Selected dropdown button in `PropertyGrid` entry has visual artifacts on Windows 11

See original GitHub issue
  • .NET Core Version: 3.0, 3.1, 5.0, 6.0, 7.0

  • Have you experienced this same bug with .NET Framework?: Yes, at 4.7.2 and 4.8, but in a bit different manner (see the screenshot below)

  • OS Version: Windows 11 21H2 22000.318

Problem description: When the drop down button is selected with the mouse cursor, there’re some visual artifacts on this button: image

This button at .NET Framework 4.7.2/4.8 at Windows 11 also have some kinds of disruption: image

General ComboBox control and ComboBox in the DataGridViewComboBoxColumn look fine at Windows 11 though: image image

Expected behavior: The button should look the same way it looks at Windows 10: image

Minimal repro:

  • Build and run the project from the attached zip file at Windows 11
  • Click on PropertyGrid entry named Flag to make the ComboBox button visible
  • Point the mouse cursor at the DropDown opening button (with down arrow) button

I will be sure to document that our best experience is on the latest OS builds. But I’m so glad this was filed so we can refer back to it!

@ArtemTatarinov is this something you suggest we change in our codebase?

No, that’s just in case, for now at least.
