I have a problem that i cannot get my shkval in my left screen with my right screen being the main monitor (position 0,0). I know it will probably have to do with negative coordinates but is their a way around it? Can i (without making my left monitor primary or physically switching my monitors) get the shkval on my left monitor? (either with a tool or is their a special way of putting in a negative value in the lua files?)
