@Carpetsmoker
I was going to suggest trying XXA accelration instead of default EXA, but that also does not helps:

You also load extmod twice (once normally, once without xfree86-dga extension), GLcore is propably not used any more, but these should also be harmless since some longer time Xorg knows better ...
Code:
Section "Module"
	Load "GLcore"
	Load "dbe"
	Load "dri"
	Load "extmod"
	Load "freetype"
	Load "glx"
	Load "record"
	Load "xtrap"
	
	SubSection "extmod"
		Option	"omit xfree86-dga"
	EndSubSection
EndSection
There was time when these two helped a little:
Code:
% export LIBGL_ALWAYS_INDIRECT=1
% export INTEL_BATCH=1
You may also try this one:
Code:
Section "Extensions"
  Option "Composite" "enable"
EndSection
You may also check these in graphics card section:
Code:
  Option     "AccelMethod" "XAA"
  Option     "XAANoOffscreenPixmaps" "true"
  Option     "AddARGBGLXVisuals" "true"
  Option     "DRI" "true"
  Option     "UseFBDev" "true"
  Option     "PageFlip" "true"
  Option     "TripleBuffer" "true"
  Option     "FramebufferCompression" "false"
  Option     "AccelMethod" "EXA"
  Option     "RenderAccel" "true"
  Option     "EnablePageFlip" "true"
  Option     "MigrationHeuristic" "greedy"
  Option     "ExaNoComposite" "false"

  # Enable offload of Motion Compensation (XvMC)
  Option     "LinearAlloc"             "16384"
  Option     "Cachelines"              "2048"
  Option     "XvMCSurfaces"            "7"
... but I am no 'OpenBSD person' and these options are GENERAL intel driver options.
