mouse freezes in the center of the screen and system hangs

[Andres Selli]

mouse freezes in the center of the screen and system hangs. It is impossible to move the mouse in a coordinated way, it moves, but for example then moving over the hidden link (some preview window of an item or smf similar), then it tries to open it without the actual click by user - the windows are opened just by moving over it and in the end nothing works - the computer has to be shut down from the power button. I have tried to reinstall, I had 18.10, now 18.04 - situation is still the same. The bug seems to be appearing randomly, maybe a bit more often while using Facebook.
