Memory Leak in Make Layer with Shadow node

Steps causing the bug to occur

  1. Run attached patch
  2. After a few minutes OS X gives warning of low memory as suspends Vuo

How did the result differ from what you expected?

Expected patch to not use up all system memory

Other notes

  • Vuo version: 0.8.0
  • macOS version: OS X 10.9

Can you please tell us what version of Mac OS you are using, and what graphics card?



NVIDIA GeForce GT 650M 1024 MB

I confirmed that this is leaking. We’ll make sure to get this fixed in the upcoming Vuo 0.9 release.

The major leak is in the Make Layer with Shadow node. If you replace that node with Blur Image and Invert Image Colors, it’s better (it still leaks slightly, but you should be able to run it for a couple hours before it uses up all your memory). I’ve attached a modified version of your composition.

I can see the attachment?

That’s because I forgot to attach it… :^] Second try…
