Hi,

Just to give additional info to any would-be bug-squasher :

So... been grappling with this problem the last couple of days and I may have
found the problem. It seems to be something to do with my dual-monitor setup.
Simply, if I remove my 2nd monitor from the X-server (via the nVidia drivers),
the tearing goes away. The moment I re-enable it, the tearing comes back. This
is independent of whether I had compiz-effects on or off. I.e. :

- When I disable compiz but still have two monitors active, videos still screen-tears).
- Same behaviour in XCFE and IceWM too (and all scenarios where compiz/composites have been disabled)
- None of the other fixes work (e.g, de-interlacing, output to OpenGL, sync-to-vblank, etc...)

Thus, my earlier suggestion about it being something to do with Fedora's
"special" livna drivers is wrong.

So far, only turning on/off that 2nd monitor works. Perhaps... can any of the
prior fellow bug-reporters confirm this please? Did they have this problem with
single or dual-monitor setups?

Also, for those not aware, there is an Ubuntu-Forums thread linked to this bug :
