I suspect bug 1359709 or bug 1361970 might be the culprit here, but I guess Matt can tell for sure.

And here is a screenshot of the problem.

Only reproduces with layout.display-list.retain set to true, so this shouldn't be an issue for 58 once we ship.

This also reproduces with the settings button on the main page (next to the Day/Week/Month/etc dropdown).

Tracking for 59 since that's when we're aiming to ship retain display-list.

The regression range from comment 0 is from before the retained display list pref was added, so I don't see how this can be a retained-dl issue.

I'm confused, I specifically verified in comment 2 that it only reproduces with the retained-dl pref set. Isn't that evidence enough that it is? :)

Looks like this is working on current trunk now.
