Every time I run a particular application (a ~20 year old one, which changes the screen resolution) my mouse sensitivity is lower after I exit (and screen resolution goes back to normal).
At first, I just went to "Mouse Settings -> Cursor Speed" and increased it, but every time I ran the application I had to increase it more and more afterwards. I'm now at the limit of mouse sensitivity, and cannot increase it any further. The mouse is slower than ever.
I've even doubled mouse speed using Regedit, but after using the application a few more times even that's not enough! I've also tried removing the driver and reinstalling it, to no avail. I've tried multiple different mouses/mice, and that doesn't seem to be the problem.
I now seem to be stuck with a slow pointer, "maximum" cursor speed setting, and seemingly no way to make this better.
How can I fix this??
(I want to reverse this problem, rather than just go into Regedit and find a hacky way of increasing sensitivity further beyond 2x. I'm using Windows 10.)
