All planet portrait in the selection area (the bottom left ui grouping) disappear after I load a saved game. Between re-loads any new colonize planets have a portrait but they disappear once I save and load the game. The issue started with the 5.3 opt-in and continues in the full 5.3 release. I have a Radeon HD 6900 driver version 14.501.1003.0.
The Colonies selection box is not affected.
