Problem summary
Convolve2 results in the error "Convolve2 node Error: filter input is missing rgba".
This issue can be reproduced by moving the Viewer window while the Convolve node is playing.
This issue occurs with and without GPU acceleration enabled within the Convolve 2 node.
Customer reported version
nuke.10.0v5
Customer reported platform
fedora
Steps to reproduce
1) Launch Nuke
2) Open the attached Nuke Script and paste the example code from the Stickynote Node into the Script Editor.
(shift+f4 is the hotkey to launch the Scripting workspace)
3) With the viewer connected to the node named "Convolve 4" and the node selected run the script. (highlight the code and press ctrl+shift+enter)
Result:
4) With the script running middle mouse over the viewer and try to movie the viewer, eventually the script will cease and print the error "Convolve4 node Error: filter input is missing rgba"
Workaround
Use the non-GPU accelerated Convolve1 node. You can do this by pressing "x" while in the DAG(Node Graph) and in the TCP command type "Convolve". This will create a new node and you can verify its version by pressing "i" while hovering over the node. While not ideal it will allow you to utilize the Convolve node without GPU acceleration.

The Convolve2 Node should not display an error, causing a black Viewer
Actual behaviour
Error occurs causing Nuke to print the error: "Convolve4 node Error: filter input is missing rgba"
