Composition crash with feedback loop

Steps causing the bug to occur

  1. Open up the composition
  2. Start a syphon server with quartz composer or similar video input (ie. simple Facetime “video input” → Syphon Server patch)
  3. Run composition
  4. Wait/click. Comp crashes. SOMETIMES, the comp crashes and the Editor then HANGS, and must be forced quit. Sometimes it’ll have a spinning wheel at “Stop” and freezes other times it just doesn’t seem to notice that the comp crashed, still shows it playing, and Editor freezes.
  5. (optional) make edits to the comp while running, and watch it crash/freeze, etc.

How did the result differ from what you expected?

Expected composition to:
a) Continue running
b) Crash and provide a crash log/debug info/trace info

Comp is a summing image feedback loop (it should take the maximum pixel value and retain it, so create ghostly fx)

Have you found a workaround?

Not really. Sometimes it’ll run for a little longer, but ususally crashes.

Thanks for the report, @joeladria. I was able to reproduce the crash. We’ll try to get this fixed soon.

@joeladria, we believe this issue is fixed in Vuo 0.8.0.
