Yeah, I realized that, It's still odd behaviour, in both cases Chrome caps =
FPS
to refresh rate (this case 85FPS), but using DRI3 using mutter/clutter, for
some reason it creates continuous stutters, even tho FPS is the same and all
other parameters are equal. It really looks (when viewed live) as if FPS is=
not
equal to refresh rate.
Just wanted to inform you guys on this, it is still probably mutter/clutter
configuration problem in the code (since it happens only there), it doesn't
follow configuration in .drirc as other WM's.
