ID 580906 - UI performance decreases when a Sync Session is active

Problem summary:
UI performance decreases when a Sync Session is active
 
Customer reported version:
Hiero 15.1v1
 
Customer reported platform:
Rocky 8
 
Steps to reproduce:
1) Launch Nuke Studio and navigate to File > Import File(s)... to import some footage.
2) Add a Clip to the Timeline.
3) Repeatedly use the Alt+G hotkey to create multiple Grade Soft Effects, noting the performance and responsiveness:

4) Open the Sync Session window and Host a Sync Review.
5) Repeat step 3, observing how the process is noticeably less responsive:

 
Expected behavior:
UI actions should not become less performant when a Sync Session is active.
 
Actual behavior:
Performing any actions on the Timeline, such as creating Soft Effects, can take longer to complete when a Sync Session is active. This may be more noticeable with some actions/Soft Effects/etc. than others, so the slowdown might be more obvious when using ColorCorrect Soft Effects for instance.
 
Workaround:
No known workaround at this time.
