ID 384248 - Nuke UI slows down when @ symbols are displayed in the Node graph

Problem summary
Nuke UI slows down when @ symbols are displayed in the Node graph.

This can either be on one node with lots of @ symbols, or many nodes with @ symbols, both of which need to be followed by 2 or more ascii characters.

The @ symbols need to be visible, so if you zoom out, the issue no longer occurs.

Steps to reproduce

1) Open Nuke

2) Create a StickyNote node 

3) Set the label to @@@@@@@@@@@@@12

The Nuke UI will now slow down, duplicating the node makes the responsiveness when navigating the Node Graph worse

Workaround
Use @ instead of the @ symbol
