David the issues reported in items 1 and 2 have been fixed in rev#71156. Issue 3, you are correct in that it is caused by another formatting bug, as we use the same engine to render the errors and tool tips. Item 4 is more complex. It seems to be related to the docking mechanism and is only apparent because the Errors and Warnings tool is based on a new optimized tool framework in 6.1. If you can find a reproducible, this would help greatly.
