Problem summary
When reviewing Roto footage in the Viewer tab, it can be useful to view the Roto playback without the footage getting in the way.
This could be done on Nuke10.0v6 via disconnecting the viewer while the Roto node is selected, but appears to have broke with the Nuke10.5v1 release.
In Nuke10.5v1 & newer, The Rotoshape will freeze in playback and will only update after pausing the viewer.
Nuke10.0v6 ( Working )
Nuke10.5v1 & Newer ( Incorrect behaviour )
Customer reported version
nuke.11.0v2
Customer reported platform
centos6
Steps to reproduce
1) Open Nuke, Create a CheckerBoard node
2) Create a Copy node and attach the CheckerBoard to 'B' input
3) Create a Roto node, attach it to the Copy node's 'A' input.
4) Animate a shape in the Roto node over a few frames.
5) Create a Premult under the Copy node's output and view it.
6) In the Viewer tab, play the animated shape.
7) Disconnect the Viewer and playback the Rotoshape
Result: The Rotoshape will freeze in place until the playback is paused.
Workaround
Attach the viewer to a default Constant, while reviewing the Roto playback without footage. (Make sure the Constant is the same resolution as the Rotoshape)
