  Intel driver incorrectly renders some UI elements

Status in “xserver-xorg-video-intel” package in Ubuntu:
  Fix Released

Bug description:
  Some UI elements from wine and fvwm don't render correctly when using
  the Intel driver. This can be observed in screenshots shown in the
  following links:

  https://bugs.freedesktop.org/show_bug.cgi?id=28798

  These issues have been attributed to errors in UXA utilising the 3D pipeline for core rendering.
  Upstream has disabled this to resolve this issue for now.

  I have applied their patch (commit: 855ced5a4eb67e287001ae22cb6489639c548cfa) to test this fix, which works for me here:
