Created attachment 80882 apitrace dump for glxgears I am seeing what appears to be the same error. It is reproducible 100% of the time with glxgears.
I ran glxgears in apitrace (causing a segfault). Attatched is the raw apitrace. Is there any other data that I can provide that would be useful? Hardware is an Intel i7-2860QM. The segfault is visible in the apitrace replay. $ apitrace replay glxgears.trace apitrace: warning: caught signal 11 1357: error: caught an unhandled exception apitrace: info: taking default action for signal 11 gdb output for glxgears: Running synchronized to the vertical refresh. The framerate should be approximately the same as the monitor refresh rate.
