I'm using Deepin v20.9 (no time to move my files to install v23 yet...) on a projector with kb+mouse combo on the bed (using bed sheet as mouse pad/mouse movement surface). The mouse movement in Deepin feels like I'm on a skating rink, the cursor rarely stops at where I want it to stop. It feels very slippery. In constrast when I boot into Windows 7 on the same machine, the mouse movement is very precise.

This is one aspect that makes Linux a toy operating system for kids. I'm sure problems like this won't be present at all in other OS architectures like OpenHarmony.
