I've noticed a couple of UI problems encountered when viewing data reports in various areas:
1) When a data report is in a widget, some of the information on the far right is cut off. Maybe adding a horizontal scroll bar to widgets would resolve this?
2) When viewing reports in a full page, sometimes the filter bar will cover up the first couple of records. This doesn't happen all of the time, and I have been unable to find a common link in instances where it does.
