Graphical glitches in WPF apps caused by Nahimic service
This is a strange one - after upgrading to Windows 11 preview I expected to get a few problems and assumed this was one of them. Apparently it affects various versions of Windows though and is caused by the "Nahimic service" which I believe came with Sonic Suite and is related to my new Asus motherboard. After setting this service to disabled I no longer get the graphical glitches in applications such as Fork GIT client, Visual Studio Installer and Choco GUI.
