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.
