Public bug reported:
I have a Dell XPS 17 with a 3,840 x 2,400 screen and an external monitor
with 3840 x 1600 resolution. When I use only one of them it works
totally fine. I use the external monitor without scaling and my notebook
display with fractional scaling of 150%. But when i want to use both at
the same time, my mouse starts to be slow. So in this scenario i have
the external monitor at 100% and the notebook screen at 150%. Everything
works fine expect the mouse which is slow,on both screens. What I found
is, when i set both my screens to 200% while fractional scaling is
enabled. The issue is gone. Same with 100%. But as soon as I start using
fractions, the mouse is slow again. I don't believe it is an power issue
because my hardware is mostly in idle. Also, i tried different mouses
over Bluetooth and USB but no change.
I am currently using 20.10 but had the same issue with 20.04. But when i
use Wayland, the problem is gone.
