Firefox Tearing when Scrolling - How to enable Vsync.

Peace ppl!

I'm experiencing firefox tearing issues/visual artifacts when smooth scrolling is enabled on aur/firefox-pgo 3.6.6-1.
One way to solve this is to enable vsync. Simply enable desktop effects on kde4 and enable vsync.

$ glxgears
Running synchronized to the vertical refresh.  The framerate should be
approximately the same as the monitor refresh rate.
263 frames in 5.0 seconds = 52.432 FPS

The fps is close to the monitor refresh rate of 60Hz.

The weird thing is if I disable desktop effects thereafter, the vsync setting still stands!

Is there a way to enable vsync without going through all this?
Perhaps through an xorg.conf setting. (Don't have one now; not required)

Thanks in advance!

Re: Firefox Tearing when Scrolling - How to enable Vsync.

vsync is not linked to 3d effects....usually 3d renderers use vsyng to avoid tearing.

in your case it might be one of the many bugs hitting the new dri drivers / xorg / kernel ..

if you run comiz, run it with --indirect-rendering

if you have an intel gpu, disable flipping (man intel)

thats what i did to help.

IIRC Chromium doesn't have that issue.
