Eliminate annoying line when scrolling in browser - Intel i915 graphics

[robinc]

Having just 'upgraded' to a 4 year old Acer X3995 with Intel i915 on board chip, I've been annoyed by the line of distortion across the screen when scrolling with any browser.

The normal disable Hardware Acceleration etc makes no difference.

Solution:-
/usr/share/X11/xorg.conf.d
Create a text file 20-intel.conf

Code:

Section "Device"
   Identifier  "Intel Graphics"
   Driver      "intel"
   Option      "AccelMethod"  "sna"
   Option      "TearFree"    "true"
   Option      "DRI"    "3"
EndSection

Reboot - sorted.
