I always thought this was a QEMU or LookingGlass quirk, but now that my work laptop has Windows 11 it keeps happening there as well.
Sometimes after hovering an icon in the taskbar (so the preview pops up) and unhovering it, the whole UI becomes semi-unresponsive until I hover the same icon again and interact with the preview. Good fucking job, Microsoft.
