This is a strange behavior I am still investigating, but it appears:
- When we open the MAST panel and dock it, anytime we toggle any other docked panel (aka maximize then minimize them using Spacebar), there is a long delay in Editor (several seconds), and then MAST panel's image preview are all gone.
- At first I thought this has something to do with shortcut conflicts, but after changing it, the same issue persists.
- The editor hang doesn't happen if the MAST panel is closed or not docked.
This is best illustrated with screenshots:
