I can confirm that the problem is present with both the intel and the
modesetting driver on Braswell systems. The exact symptoms differ for
each, but in both cases it is triggered when the mouse touches the left
limit of the screen. With modesetting, it seems to "stick" until you
move the mouse away from the left side. With intel, touching the left
side starts a flickering that persists even after you move the mouse
away. Mainly, just the mouse cursor flickers, but the whole screen will
flicker when doing graphics intensive tasks like fullscreen video or
gaming. Sometimes, the mouse flicker can be so bad it becomes nearly
invisible.

I have made full report on the bug report thread opened by Salvatore.

The good news is I found a workaround, you can use xrandr to scale the
display to 0.9999x0.9999 and this prevents the issues in both intel and
modesetting. This can be done in your .xprofile in your home directory
to take effect at login. It does come with a slight performance penalty,
but it's preferable to the glitching that happens otherwise (at least
until someone fixes the regression).

xrandr --output HDMI-3 --mode 1920x1080 --scale 0.9999x0.9999

Replace "HDMI-3" with the name of your display (can be found by running
xrandr with no options).
