the changelog is available here:

	https://github.com/yshui/picom/releases/tag/v11-rc1

picom now tries to set itself as real-time.  I've commented out that
part since it uses a function we don't seem to provide
(sched_setscheduler), but it's not a big deal.

However, I had again issues with the visibility of OpenGL symbols.  This
time the 'usual' workaround didn't work.  See the two diffs below.  It's
ugly, but at least I can confirm that the glx backend works for me
(amdgpu if it matters.)  Any help understanding this is welcome :)
