I also made same bug under xcb/protocol https://bugs.freedesktop.org/show_bug.cgi?id=93414 , apologies for this, I am not sure where to file this problem. I will close one of the two bugs when I am pointed to the most appropriate component of the two. I think it looks more likely to be app/libX11/XCB related so far, so let's continue there for now. |

Application that renders using libva/vdpau/opengl hangs after a few minutes of operation (always reproducible within 1-15 minutes usually).
