Compton freezes the desktop

[Samsonnine]

Hi,

I have a Nvidia graphic card, and I use the Nvidia driver.
When using compton, this one freezes the desktop randomly when I select an item and do a "drag and drop".
The only way to get out of this freeze, is to go to another tty, and then come back to the graphical one.

I noticed thatt using only marco or metacity whitout compton "solve" the issue.
Using compiz is fine too, no problem.

I need to use compton because of tearing problems.
So..Is anyone in the same situation ? Can you reproduce the problem ?

Thank you.
