I'm running Debian Testing with the default desktop environment installed from tasksel, on an Intel i7 system (64-bit install) with an Nvidia GTX 760 GPU. (No closed drivers installed, just whatever comes with the system.)
I'm having problems with tearing. When you drag windows around quickly, or play any video, severe vertical tearing is obvious. I Googled the problem and found many suggestions to put the following into /etc/environment: CLUTTER_PAINT=disable-clipped-redraws:disable-culling CLUTTER_VBLANK=True But this made no difference to me. (I Googled CLUTTER_VBLANK and found documentation suggesting it can only be set to dri or glx, but neither of those made any difference either.) Is there anything I can do to fix/enable vertical sync to stop the tearing, or is this a bug? Happy to provide more information if required. -- David Glover-Aoki http://david.gloveraoki.net/contact
