I'm not sure if this issue persisted in other versions. I'm on version 5.1.12 running on Windows 10 Pro x64 build 1607 on a Surface Pro 4 with three monitors.
Here's a snip of the issue. You can see that the last written date is cut off by the status bar at the bottom.

It's fine if viewed in the "resources" section, but when viewing in the "campaign" section to preview the specific block in the timeline this is what is shown.
I cannot clip more for viewing for privacy and copyright reasons (just covering myself).
I think the issue is that there are player controls at the top of the picture and they push the image down, but the image doesn't respect the boundaries of the status bar at the bottom.
