Pointer visible but black screen below

[thomas-vincent]

This looks like a great tool!

However, I cannot get it to run properly. I see the red pointer but the screen below is all black...
My system is Linux Ubuntu Mate 1.24, Kernel 5.4.0.

For me, if I run it with i3, it will basically take over with a black window and nothing else is visible. I need to kill it from another virtual terminal (the ones with Ctrl+Alt+number).

If I run a compositor like compton also (you can start it during the i3 session from a terminal, just make sure it keeps running in the background), then it works as expected.

Using xcompmgr here, works great!

Sounds like at the very least the tool should check to see if there is a compositing window manager running and abort at initialization if not. Ideally though, it'd use a fallback method that doesn't rely on a screen-sized Cairo canvas (maybe dynamically moving and resizing a tiny red window slightly below-right of the cursor?). Hmm.

I don't presently have time to revisit this tool, but I'd like to in the future. Leaving this here as a note-to-self. Pull requests also welcome in case anyone else has the cycles.
