Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: FLTK viewer Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: D. R. Commander (dcommander) Assigned to: Pierre Ossman (ossman_) Summary: Double buffering doesn't work properly in new viewer Initial Comment: Double buffering doesn't seem to work properly with the FLTK viewer, nor the latest Java viewer in trunk (most likely because the Java viewer is borrowing the FLTK viewer's logic.) The easiest way I've found to repro this is to run GLXspheres in VirtualGL and add 200 ms of artificial latency to the server: sudo tc qdisc add dev eth0 root netem delay 200ms vglrun /opt/VirtualGL/bin/glxspheres -i Rotate the spheres, then stop, then start rotating them again. You should observe "notches" disappear from the upper spheres, most likely due to some of the solid rectangles not being rendered prior to the frame advancing. I also observe frequent tearing artifacts, whereby only half of the frame is drawn before it advances. I observe this most readily on a RHEL 6 client (nVidia GeForce) connecting to a RHEL 5 server, but I also observe it to a lesser degree when using my Mac Mini as a client. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=1126848&aid=3531487&group_id=254363 ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
