Looks like we are dealing with something completely different, even though somehow fence-related. Also FWIW, running weston-simple-egl with the -b option (eglSwapInterval 0) leads to the same behavior as glmark2. I will keep investigating where/why the fences are blocking.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
