In Brief

  • BUG-233107 “Objects failing to render is happening more frequently of late” – is rising slowly up the priority list, however, from the discussion at the meeting:
    • There may actually be two issues at work, with some conflating them into a single problem, and / or there is an issue impacting both the viewer and the simulator.
    • Both issues may additionally be cause a race condition with messaging, leading to rendering / rezzing problems.
    • It is suggested, pending an actual fix, alt-camming out a good distance, waiting several seconds and then ESC-ing the camera back to its default position can fix both issues by forcing the viewer to call for a complete scene update.
    • One of the problems is most persistent on either initially logging-in or following teleporting into a region; it rarely happens on crossing between regions via foot or vehicle.
