Consider picom fork with round corners for glx backend

[wesbluemarine]

This fork should provide round corners for glx backend.

Hello @wesbluemarine thanks for the suggestion, can you elaborate? We already have rounded corners and I don't know anything about the glx backend. What would be the advantage of switching to that fork?

[wesbluemarine]

In addition to the increased performance, glx is in some cases the only way to avoid tearing. With Intel modesetting driver you can't have Xorg "tearfree" anymore, so there is a need for an implementation from the compositor (picom).

Thanks for the explanation @wesbluemarine. I always say "don't fix what is not broken" - so far I did not notice anything was wrong with helloSystem on Intel GPUs, but maybe you can demonstrate what the issue is that this can fix? (I noticed that the Welcome animation is less than perfect - is that the tearing you are referring to, and would it go away using this fork?)

I can post a screencast or a recording from camera. Tearing is what happend when you move your windows and they letteraly tear (2 or more pieces), it's not a "smooth" experience. https://www.youtube.com/watch?v=IJeX35wbZY4
