2 annoying bugs/glitches on Cubase 9.0.30 WIN 10

I have 2 small, but annoying issues with Cubase. First one is, whenever I’m importing something, when I try to select file with my mouse it goes straight to the bottom left of the screen

Second one is, when holding down the Alt key over MIDI tracks, the cursor can be seen glitching, but when I hold down the Alt key over audio tracks, it acts normal

Hopefully some of you may help me,
