Well I have the exact same issue. It is not wireless interference since the problem occurs wired and I tried the earbud method to clean the lens that Madara suggested but it didn't seem to bring any dirt out and there was no behaviour change.]
Same issue starting 2 days ago with a Reddragon Perdition Laser Mouse, I have been using since more than a year and more than 6 months on same black mouse pad. the tracking ofhand movements is very irregular on that mouse pad, first I clean the sensor area of the mouse , on windows desktop it seemed to move normally but not in PUBG, but after a while did not respond fast moves anywhere. I updated software and drivers from brand web page. but no result. On my Laptop using a orange carboard it seems to respond fine, but when I get back to my PC and black mouse pad same issue, and it seems to get worse with every intents. On laptop I did not install any special drivers for this mouse and good response. Both PC and Laptop run Windows 10.
I am lost , my old Microsoft sidewinder mouse works perfect with my PC and black mouse pad. Very odd, I uninstall Mouse in device manager in case it was a conflict after win10 update with common mouse drivers.
Any other suggestion beside black magic!
