Comment 1 for bug 281065

Same problem since the last upgrade yesterday (intrepid beta), while it works quite fine before, just some very small glitches on the systray for example in hardy.
Firefox is unusable with this problem.

It happens when --loose-bindings is enabled in compiz (which is the default if the card is nvidia).
If I disable --loose-bindings :

/usr/bin/compiz.real --ignore-desktop-hints --replace --replace core ccp
instead of
/usr/bin/compiz.real --ignore-desktop-hints --replace --loose-binding --replace core ccp

there is no problem (except of course compiz effects are far slower).
