The Tracker's pattern and search window handles do not consistently update in the Viewer while Tracking on macOS
 
Customer reported version:
Nuke 16.0v4
 
Customer reported platform:

Steps to reproduce:
1) Launch Nuke on macOS and paste the following nodes into the Node Graph:
 
CheckerBoard2 {inputs 0format "8192 6144 0 0 8192 6144 1 8K_CubeMap"name CheckerBoard1}FrameRange {first_frame 1last_frame 100time ""name FrameRange1}Transform {translate {{curve x1 0 x100 2000} {curve x1 0 x100 2000}}center {4096 3072}name Transform1}
2) Create a Tracker node and attach it to the Transform node 
3) View the Tracker, and open its Properties
4) Press the add track button
5) In the Viewer, press the Track To End button, or use the V hotkey
6) Observe how the pattern and search windows do not update consistently:

 
Expected behavior:
When tracking with a Tracker node, the Viewer should draw the pattern and search window overlays and update every frame smoothly, as it does on Windows:

 
Actual behavior:
When using the Tracker node on macOS, handles in the Viewer like the pattern and search window can freeze and not update consistently.
 
Workaround:
No known workaround at this time.
