Note that I suggested xcompmgr -a, which should be lighter than -c.

These are all defaults, no need to specify them explicitly in xorg.conf.

I missed this before. Why did you disable this? Does not disabling it help?

This is probably why mpv isn't working well. Any chance you can try if
the attached xf86-video-ati patch helps for this?
Note that you can always use mpv -vo x11 to get basically the same video
experience as with Option "NoAccel".
