For mouse related issues, see if there are updated mouse drivers available.
Also, if you are using a UHD or 4K (or higher) display make sure that you have a high resolution mouse.

See if there is any difference between using the classic graphics driver as opposed to the new one (applies to SU 2024+).

If all else fails (including on Windows rerunning installer and choosing Repair) find a memory test utility and test your system RAM.
