I had a problem after some updates (windows update but maybe nvidia too ?) : mouse jump to center of screen, and windows opened part outside of the screen are moved full in current screen.
I didn’t know why and it was very annoying to have this every a few seconds !
And I found the cause : I have a 2nd screen connected on board (videoprojector) but not ON (just the cable connected).
I just turn ON electricity (to put videoprojector on standby) and the bug was finished.
I think that the graphical driver has a bug when it wants to detect all connected screens, it seems to find some electrical information with cable connected but screen don’t “answer”.
Hope it helps !
