Program view goes white when video paused?

[sjchiggins]

My program window goes white when I hit pause while editing.  When I click and drag the playhead I can see the video, but when I release the playhead the program window goes white again.  Might this be due to my image size, which is much larger than the 640 x 360 in the tutorials and where I don't have this issue?  The image size I am using defaulted to 3840 x 2160.

I solved the issue by changing the paused resolution to 1/8, which I accessed by clicking on the "wrench icon" in the lower RH corner of the Program Window.
