Screen partly unusable after connecting 2nd display

[xouns]

On ACER AS 1810T, after connecting a 2nd display (DELL) running resolution 1920x1080, the 2nd display did not refresh apart form the mouse and the top bar. Screens did not show, although the mouse cursor changed whenever a hyperlink was supposed to be under the cursor. Also, a part of the original screen (laptop monitor) had the same problem. Windows went full-screen whilst ignoring a part of the screen.
After restarting the X-server (ctrl-alt backspace) the problem was solved.

Hi, what graphics driver are you using, also are the resolutions of the two screens identical? I presume from the description that you're running the two screens in "clone" mode?

what happens if the screens are cloned? could you also try to put screens in 'one above the other' configuration from 'monitors' settings and let me know if the issue happens still, this could somehow be a hardware limit.
