If so, please set a breakpoint at >_mesa_error and provide a backtrace. From within _mesa_error, could you also >print the value of ctx->API? I'm not skilled enough with GDB, sorry, but I could use DBG(...) to print checkpoint informations in logcat. Apitrace collection is possible on kitkat-x86 while it is still very difficult to perform on lollipop-x86. We are trying to collect apitrace on kitkat-x86, while dreaming of it on lollipop-x86, but I would proceed on OpenGL ES version checks. >From some out-of-band communication there was a suggestion that the problem >could be because of uses of GL_PIXEL_UNPACK_BUFFER and GL_PIXEL_PACK_BUFFER in >meta. Meta usually sets the API to API_OPENGL_COMPAT to avoid problems like >this, but it's possible that was missed. I believe PBOs were added in OpenGL ES >3.0, but i965GM is an OpenGL ES 2.0 part. pstglia, a fellow member of Android-x86 forum came to the same conclusion that PBO are OpenGL ES 3.0 and the binding with GL_PIXEL_PACK_BUFFER/GL_PIXEL_PACK_BUFFER targets fails returning NULL and causing the 0x500 error. I think that API_OPENGL_COMPAT is definitely worth a try. Do you have a proposed patch for us to test and report?
