Using LIBGL_DRI3_DISABLE=1 works, so it's really DRI3 specific. I attached gdb, here's the bt: #0 0x00007fa40950507d in poll () from /lib64/libc.so.6 #1 0x00007fa4084f5c22 in ??

() Yeah, this is not terribly good (most of my stack isn't build with debug symbols), from from the looks of it, this seems similar to <a class="bz_bug_link bz_status_NEW " title="NEW --- - Intel DRI3 driver hangs WebKitGTK" href="show_bug.cgi?id=81623">bug #81623</a> libxcb is git tip though, so the fix proposed in the other bug doesn't work for me (I doesn't appear to work for the WebKit issue either).</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
