ID 598704 - Node Graph Viewer Masks are not displayed correctly on Monitor Out devices

Problem summary:
Node Graph Viewer Masks are not displayed correctly on Monitor Out devices
 
When Viewer Masks are enabled, Viewer Guides will also not display correctly.
 
Customer reported version:
Nuke N/A
 
Customer reported platform:
macOS 14
 
Steps to reproduce:
1) Launch Nuke and create a ColorBars node in the Node Graph
2) View the ColorBars, and open the Viewer Properties by double-clicking the Viewer node
3) In the Viewer tab, set the safe_zone to title safe, masking_ratio to square, and mask_mode to half: 

4) Switch to the MonitorOut tab then Enable Monitor Out and select a Device:

5) Observe how the the image displayed in the Monitor Out device does not match the Node Graph Viewer:

 
Expected behavior:
The Node Graph Viewer's safe zones/guides, mask regions and mask modes should be output to the Monitor Out Device, the same way these options behave when using Monitor Out in Nuke Studio. 
 
Actual behavior:
Monitor Out Devices will not display the same result as the Node Graph Viewer if the Viewer's mask_mode is set to anything other than "none". The "half" and "full" mask modes will be displayed in the Monitor Out Device as "lines", while all three options prevent the safe zones/guides from displaying correctly.
 
Workaround:
No known workaround at this time.
