--- Comment #5 from Thespikedballofdoom thespikedballofdoom@gmail.com --- Actually, I found something like a fix, a bit nuclear as it's just 'disabling' (setting the appearing delay to a really high number) tooltips in the registry. https://www.reddit.com/r/Windows11/comments/1mmz5b1/give_us_an_option_to_tur...
Basically, wine regedit, then go to \HKEY_CURRENT_USER\Control Panel\Mouse / MouseHoverTime, and set a real high number like 9999999.
I'm sure a wine prefix can isolate this to just foobar2000 but I don't know how to set them up yet.
