 I should clarify my comment.  The text is from firefox rendering a .gif

 The chipset:
 
 [   292.519] (--) intel(0): Integrated Graphics Chipset: Intel(R) HD
 Graphics 3000
 
 has:
 
 [   292.535] (II) UXA(0): Driver registered support for the following
 operations:
 [   292.535] (II)         solid
 [   292.535] (II)         copy
 [   292.535] (II)         composite (RENDER acceleration)
 [   292.535] (II)         put_image
 [   292.535] (II)         get_image
 
 and, so far, disabling accel seems to have stopped the problem.
