Bug Description

This tearing occurs only at the very top of my laptop's panel within about a two centimeter margin. It is usually produced in the title bar of a fully extended window moved side to side. Also occurs in this spot with Youtube videos when positioned between the first and third workspace. Had the same problem with a lower resolution panel that I recently replaced with my current one. Also see it running Mint and Arch with Compiz Fusion or Cairo Compmgr.

The laptop is a Clevo W251ESQ. System76 currently sells two nearly indentical laptops from the series, they likely have the same screens as mine. The panels I have used are the LG LP156WH4(TL)(A1) and LP156WF1(TL)(B2). Rendering with an i3-2350M as the Nvidia card must be run via Bumblebee. My Ubuntu version is 12.04 fully upgraded as of August 16th.

This will be fixed by the fix for bug 901097, which is the gles2 branch.

But until then, there is a simple workaround. In CCSM, Workarounds, enable "Force full screen redraw (buffer swap) on repaint".
