When you zoom all the way out from your EER diagram, you will notice a flicker around the sides of your diagram as it attempts to draw the gray background around the perimeter, but it then instantly get overwritten by the grid.

How to repeat:
1) Create a new EER Diagram
2) Use the slider zoom in the navigator to zoom out to 20-30%
3) As you move the slider you should notice the grey flicker around the canvas as it tries to draw the background.

Suggested fix:
This worked properly (without the flicker) in version 5.1.18, but broke in version 5.2.11

Whether it's a graphics card issue or not, this worked previously, and now is problematic.  Please ensure the redraw is happening properly so the gray background is shown to give context around the canvas.
