My Steelseries Prime Wireless only has basic functionality working. I could run the software via Wine or VM (don’t remember) but it didn’t remember the settings after a power cycle of the mouse or the PC (also don’t remember).

The scanning is done on your device. You could theoretically only overload the CSAM reporting feature if such a thing will exist.

why doesnt GNOME have a maximize button

Probably because you can double-click the window ‘bar’ to achieve the same.

I found kdenlive terrible. DaVinci Resolve is much better, but it’s closed source and has some limitations in terms of hardware encoding support (nvidia only).
