This is really a pain to bisect, there are likely several issues around. However for this one, last good commit is 8ad7c19. Looks like something in the ARB_copy_image series seems to cause things to fail, or maybe UE4 is a user for the extension. --- 8< --- commit 410fea8dd9cc0b1b500477a8b6f68c950f7c895a Author: Jason Ekstrand <firstname.lastname@example.org> Date: Fri Jun 27 16:05:37 2014 -0700 i965: Add support for ARB_copy_image This, together with the meta path, provides a complete implemetation of ARB_copy_image. v2: Add a fallback memcpy path for when the texture is too big for the blitter v3: Properly support copying between two places on the same texture in the memcpy fallback v4: Properly handle blit between the same two images in the fallback path v5: Properly handle blit between the same two compressed images in the fallback path v6: Fix a typo in a comment Signed-off-by: Jason Ekstrand <email@example.com> Reviewed-by: Neil Roberts <firstname.lastname@example.org>

Not sure where you dug that old e-mail address up from. Haven't recieved anything useful there in years. Re-assigning to my active account.

Sorry, that's what bugzilla had when I searched you in the 'Assigned to' field. Will use the new one from now on. Let me know if you need some help with this, I can try to debug as well.
