I am more and more inclined to think that the problem is in the AMD processor. Apple may be using some kind of Intel processor instructions. Perhaps a kernel patch has not been found that can fix this.
IMHO many users have a problem, but they do not see it.
I have same problem, but without sleep.

I left only VirtualSMC, Lilu, WhateverGreen and nothing.
I tried different graphics cards RX460, RX480. RX580, and same problem.
May be problem with PCI-E motherboard, don't known.
Hi guys.
With 3 monitor when I do Drag'n'Drop, a terrible mouse lag occurs.
With 1 monitor lag almost invisible, but exists.
Does everyone have this?
Ryzen 9 3900X | MSI B450M MORTAR MAX | RX580 | Mojave 10.1.4.6 or Catalina 10.15.4 | OC 0.5.8 | 3 Monitors.
