Hi @Josip_Pavic2
Which window manager are you using? Marco, Compiz, or a different one? Try changing window manager and see if it fixes it, that way we know what to blame (or what to discard) 
I tried to change the window manager to all that were on the list but it didn’t help then I returned to default one. Also created conf file in xorg named 20-intel.conf with lines but it didn’t worked Section “Device” Identifier “Intel Graphics” Driver “intel” Option “AccelMethod” “sna” Option “TearFree” “true” EndSection
