Mouse pointer have lag.

Mouse pointer behaves as if it has an invisible square attached to it. This
square covers some area next to the pointer, but it is not always clear exactly
where (a link to a screenshot is shown below, please note the white square with
some text from the previous webpage displayed in that window).

This makes selecting text difficult, as one never knows where exactly the
selection ends. Also, scrolling in some windows becomes problematic, as the
pointer shadows a part of the scrollbar. When a text is being typed, one needs
to make sure that the pointer is parked sufficiently far from the text (so, to
make a long story short, this is very annoying).

This happen with driver propietary of Nvidia Optimus. This have workround
restart sddm after login.
