Public bug reported:

If "fractional scaling" is set to 150%, then after login there is a
second cursor stuck on the screen. Confirmed on both Ubuntu 20.04 and
21.04.

It is possible to fix it by switching back to 100% scaling and then set
150% again (every time you log in). Or, probably, have it as a startup
script which I could not figure yet.

Using Wayland is not an option for me because of reasons: lack of
support from certain software such as IntelliJ IDEA so everything is
blurry there with scaling enabled plus a couple of other issues.
