Hi Lynne,
Thanks for the feedback.
Some more discussion points below.

on AMD and Intel.
Does it work on Nvidia too? Does it have smooth capture?
Does it work for 3d applications?

I understand where you're coming from and it makes sense to give it a
shot - my only fear is that we may need to use specific Xlib functions
anyway.
But let me give it a try and see where we go.

Hi Marton,
Capturing at 60 FPS 1920x1080, the difference is even more noticeable:
x11grab is choppy, xcompgrab is smooth (this time I used H264 ultrafast
to encode).
https://send.firefox.com/download
- xcompgrab: 10.32s, 18.2s, 0.38s
- x11grab: 10.20s, 11.6s, 0.22s
Definitely much more CPU usage, but the output quality can't be compared.
Please note no frames were lost/skipped, everything was processed on
time for both tests.
Thanks,
Emanuele
