Description

**Issue**
Windows 11 (x86_64) runs very slowly for even basic tasks, opening the start menu, browsing files, etc. Application windows appear to be rendered "choppily" when opening or being moved around. SPICE Guest Tools are installed, and Clipboard / File Sharing works, Automatic Window Resizing didn't work until enabling Retina Mode as per #4064.
