The white rectangles surrounding the square under the mouse are sometimes garbled after going up in the treemap.
This is not sometimes easy to reproduce. Here is a way:

1. Open https://sourcesquare.antepedia.com/view/0c7e7ffa7ffa8ec25b58521fed9d1a06997f5531.html
2. Click on the gray square in the top-right quarter. The one which is just above a smaller, bluer square. Yes, that one.
3. Go two levels upper, either with two right-clicks or by clicking on the P... in the breadcrumb.

=> You're done! Mouse over the treemap and see the white rectangle performs badly.

It seems to be related to the fact that, when drilling deep in the treemap, it sometimes dynamically splits squares into several smaller squares. This was done to save browser resources by not displaying all squares, but seems to confuse things.
