Reproducible: Always Steps to Reproduce: 1. I got this without doing anything special - I have four tab groups with a selection of tabs in each. Many are corporate intranet so I can't attach specific URLs 2. 3. Actual Results: Many of the miniature images of each tab appear to be truncated at the lower and right hand edge with the remaining space filled with black. Expected Results: The miniature images of each tab should not be truncated

Attaching an image of the tab that appears at the top left of the panorama screen. Actually I think the miniature version on the panorama screen is complete but the vertical scaling is such that it doesn't fill the full height.

Attaching an image of the tab that appears at the bottom right of the panorama view. Again, I think it's complete but in this case both the vertical and horizontal scaling has made it too small to fill the available space.

this is most certainly bug 594958
