My first screen is connected via HDMI. My second screen (ASUS MB168B) is connected via USB 3.0.
Settings -> Displays:
When I choose 'Single Display' no mouse flickering at all. When I choose 'Join Displays', there is mouse flickering on main screen but only at the upper part of the screen (~30% height,). It happens only if I move mouse cursor.
I was trying to move displays, find solutions in web, change resolutions but nothing helps here.
It's incredibly annoying. Please help.
