I have a pretty annoying problem with nvidia. I went through the NVIDIA support which redirected me to this forum.
I’m on Ubuntu 14.04 with Openbox, the NVIDIA driver version is 331.38, the graphics card is a GT630.
Under Openbox when I read a video with either Chrome or VLC, I have tearing.
If I reinstalled ubuntu with gnome3 or ubuntu-desktop (unity), I have no tearing.
I’ve tested all Nvidia drivers (331.67, 334, 337 beta) but still the same problem.
I tried to disable the composite in the xorg disable backing store in lightdm, but nothing works.
Someone would have a solution to remove tearing in openbox?
Thank you very much.
