I'm playing around with some sort of smear effect. I have a base image where I pick a small width from and smear that out over another layer which moves around. After a little while that layer starts blinking randomly. I thought about it being the picker that moves out of the to-be-picked image, but that doesn't seem the case.

What is happening here and what can I do to fix this?

This occurs on both an iMac 5K and the latest MacMini.

We tested on a couple computers at Vuo HQ and are also seeing the flickering. Not seeing any problems with the event flow. I checked if the flickers coincided with the occasional events from Fire Periodically or Smooth with Duration : Reached Target, but they don't.

@casdekker, have you found a solution? If not, I can convert your question to a bug report.

Jaymie (@jstrecker) Sorry for the late reply:

In the end I used multiple Render Layers To Window as suggested by @Bodysoulspirit. I needed the comp to split to multiple outputs. Two with the result as also shown by @Bodysoulspirit, one with a painting and a 'line picker' and one with only the 'smeared' output. This gave no flickering.

I don't know if the issue is very common, but as described, working around it gave no flickering.

No I don't know either why it is blinking. Perhaps due to some event cables, or a bug with the images on top.
Perhaps try with a Render Layers Ton Window instead, here with this method it does not flicker for me. May be better methods though.

PS : Put the vuo file in your same folder as the original one as it scans the folder WERKEN that has to be in the same folder as the file.
