MapInfo - Raster image background becomes blue in Pro 15.2

Product Feature: Workspaces
Product: MapInfo Pro


As soon as MapInfo Pro 15.2 gets minimized and another session is closed raster images display blue in the re-sized MapInfo Pro session. 


This could be reproduced from engineering but the reason for this is unclear, however, it is fixed in the builds they are doing of 15.2.2. 

So the issue may already have been known and addressed or some other fix may have fixed this issue as well.

As soon as this happens it is recommended to save the workspace with a different name to not loose any changes and re-open it. The raster images should now display again properly.
