Win32Exception when moving the cursor while Windows' User Account Control (UAC) window pops up

Describe the crash: When I try to launch my tablet driver, Windows brings up the User Account Control window (which dims the whole screen behind it). Sometimes, if I move the mouse while that window appears, Lazer crashes and gives a Win32Exception saying “Access denied”.

Logs: The only relevant portion of the logs is this one in runtime.log:

One weird thing is that the “Access denied” description is in Italian (my OS language), but that’s not very important.

Good to hear! although this issue does not appear frequently, I think this should still be opened until the game fully uses SDL as its default backend and leaves osuTK away.

Fixed in SDL as of now.
