I use a multi screen setup with 5 screens
The workspace layouts don't save correctly when using multiple screens
Screen2 is the default main screen on my setup

Workflow
Enter the standard workspace and undock the various panels and position them on different screens as below and then save the layout
screen 2 Main window
screen 5 Timeline
screen 4 Curve editor
screen 3 Content/ Scene/modify panels
Swap to the animation workspace then swap back to the standard workspace
the timeline and curve editor remain on their set screens 5 and 4 respectively
however the Content/ Scene/modify panels have moved and grouped over the main window on screen 2
This happens with all the workspace layouts, but with random results as some panels remain in one workspace but shift in another despite saving each workspace
However if I keep repositioning the panels and saving the layouts the panels eventually stop moving when switching workspaces and finally stay in place.
Also if i set out a workspace then save the layout several times before switching workspaces the panels stay in place
But if i close and reopen Iclone then the panels start moving again when switching workspaces
This clearly shouldn't happen
Attachment "workspace1" shows the final render workspace layout as i set it
Attachment "workspace2" show the final render workspace after switching out and back
the red dividers and numbers show the screens and their relative positions to each other
