So I like this MacOS feature where your cursor displays in large. I was hoping if anyone knew of such software that replicates this functionality for Linux. Considering MacOS and Linux are both Unix, and libraries are different, could X or Wayland help replicate this?
This is just the first thing I found, but I'm sure there's others for whatever you're using.
gnome may be the desktop environment, depending on your distro. it looks like this:
Showif your desktop looks like that, it's gnome (Pop_! OS, Ubuntu/Kubuntu, and a few others come with it by default)
On my Mac running yabai it sometimes gets into this weird state where the mouse does this as it toggles rapidly back and forth between some windows. No idea what causes it...
On Linux I run i3 which kinda negates the need for the mouse finder since it will move the cursor to the active window.
I guess I didn't remotely answer you question though!
