I haven't gotten around to testing your suggestions yet. I'm quite busy at the moment. However I do think I have found a solution thanks to 'iphipps' at ask ubuntu. Thread: https://askubuntu.com/questions/1237310/laggy-mouse-pointer-in-ubuntu-20-04?noredirect=1#comment2085973_1237310 Disabling 'zoom' from 'universal access' seems to fix the problem. If you would like me to do any other tests, I'll be happy to help.
