So, I have the same problem, when I press F11 twice, the cursor disappears completely. Additionally, when recording the screen, e.g. using OBS, everything looks great. I tried reinstalling the launcher, changing the version, removing Java (the one downloaded by the launcher itself) and still the same. (I'm attaching the video above)
