I also made an apitrace which you can find on the following link, if someone is interested into looking at this issue:

Under the risk of adding noise here, I tried this apitrace on a intel HD4600 (haswell). I got several visual artifacts (in addition to be really slow), getting several performance related debug warnings. For example, at the initial phase, where it is mostly compiling shaders:
It does the same when playing the apitrace with my card, but those artifacts where not there at recording time. I think they are due to fake calls injections.
There is an explanation for this on the tracing section of the following link:
