This week Nvidia released a driver update that officially supports the latest GeForce RTX 2080 Super and optimizes the GPU for Wolfenstein: Youngblood. It turned out, however, that it also causes some problems for the users' mice. There have been cases where, after exiting any game, the cursor behaved irregularly, and even an additional cursor appeared on the screen. Nvidia has reacted swiftly and released a patch, which you can download here.
It is not clear how common the problem is, but there are already entries on the forums that hotfix does indeed fix errors in cursor behavior. Nvidia is explained by the fact that such bugs appear sometimes when driver updates are released very quickly.
A GeForce driver is an incredibly complex piece of software, We have an army of software engineers constantly adding features and fixing bugs. These changes are checked into the main driver branches, which are eventually run through a massive QA process and released.
As you can see, quality control did not fulfill its task in this particular case, but there is no need to take it out on Nvidia. Ultimately, the problem was solved, and if you have also encountered it, make sure you have downloaded the latest patch.
