The message-list pane reacts with a visible delay on mousewheel scrolling. Linux-only.

Reproducible: Always

Steps to Reproduce:
1. Open a mail folder containing a lot of messages to make scrollbars appear
2. Scroll the message list with the mousewheel

Actual Results:
There is a perceptible delay between the movement of the mousewheel and the movement of the message list.

Expected Results:
No delay, like the scrolling works in the message pane.

Looks like a side effect of Bug 345887. Putting

#threadTree treechildren::-moz-tree-row(odd) { background-image: none !important; }

into userChrome.css works around the underlying issue.
