Do you play with the game at what resolution? If your screen os 1080p and you play at 720p for example you might have issues.
teoretically if you just turned on "map absolute raw input" the game should not any problems like this.
but when i tried using open tablet driver, the game always had this problem you're describing. one way of fixing this
was just to play the game at 1080p, so the game resolution and the monitor are equivalent. but i didn't want to do that
cause of input lag.
i'm now using the old hawku driver and i dont have this issue. "map absolute raw input" actually works properly at low resolutions.
also, its better to leave raw input turned off, i think.
the images are the settings i actually use if you want to try the same, maybe it works.
