The 11MB file is probably useless. I got a small trace when factorio crashed very early on in the loading process (due to the radeon bug). Just loading the main menu and quitting the game results in a very big trace file, more than 100MB even in low-res mode (as it contains all the textures in low-res).
That 200MB file sounds much better. When you replay the trace, do you see corrupted graphics? I'd like to replay the same trace on my radeon card to see if it works for me, but you'll probably need to ask someone from the factorio team for permission to share that file with me (and if it turns out to work for me, share it on the mesa bug tracker so Intel devs can hopefully take a look at it, or privately with an Intel dev at least).
Edit: Looking at my trace file, I notice there are loads of "glEnable(GL_BLEND); glBlendFuncSeparate(…); glBlendEquationSeparate(…);" each frame. I'm an OpenGL noob, but this seems like a ~once-per-frame setup thing? Is there any reason to do thousands of iterations? Or maybe it's just a glitch with apitrace? Anyway, it probably doesn't hurt performance too much because it's just a setup thing and no actual heavy processing takes place when doing this? Just makes the trace file hard to read.
