Does ubuntu not support other desktops? I had little annoyances like that with fedora cinnamon, not quite enough to make me miss windows but enough that I'd notice them and wish I could adjust them, also I eventually learned that it was a desktop environment that heavily relied on some form of javascript, which likely explained why it sometimes couldn't keep up with mouse updates. But then I tried KDE and it addressed all of my issues, plus some others that I didn't even realize until I saw a better implementation, plus it's able to maintain that realtime responsiveness cinnamon struggled with (and my machine is far low end).

It's been a while since I used Ubuntu, and even then, it was just for school so I only really needed the terminal and didn't care what the GUI was doing as long as it didn't interfere with that.

Hope they update those to your liking soon in any case.
