I just bought a second monitor to use with my laptop, a vertical one. Aside from the difference in dpi, which I can live with (not easily fixed unless i blur the screen with xrandr scaling), my cursor gets stuck on the titlebar when trying to go from one screen to another. If the cursor passes the title bar, I can see its tail on the other screen but i have to go down a bit to go through. It's like a little hook, really annoying. The other screen is taller and I have to cross this spot a lot.
I don't even know how to describe this problem to google. Anyone got an idea to fix this?
