ID 548322 - Node Inputs can be offset with a Backdrop node's note_font_size knob

Follow

Problem summary:

Node Inputs can be offset with a Backdrop node's note_font_size knob.
 
Customer reported version:
Nuke 11.3v1
 
Customer reported platform:
Windows 10
 
Steps to reproduce:
1) Launch Nuke and create a Backdrop node in the Node Graph.
2) Open the Backdrop's Properties Panel, and set the note_font_size knob to a large value, such as 200.
3) Observe how the Viewer's "1" Input is displaced:
 

 
Expected behavior:
The Backdrop's knobs should only affect the Backdrop node.
 
Actual behavior:
The Backdrop node's note_font_size knob can influence how the Inputs of other nodes are displayed, but this only seems to happen one node at a time, and varies by the type of node:

 
Workaround:
Backdrops with higher z_order values appear to be prioritized, so adding another Backdrop node with a note_font_size of 11 and a z_order of 1 or greater should resolve the issue.
