To be clear, is this only with the rss tooltips or any firefox tooltip?

To test my understanding and your patience! :) Any rss live bookmarks? From the toolbar or from the bookmark menu? I'm currently trying to reproduce using iceweasel-10, if that matters, with the anandtech.com rss bookmarks.
Looks also to tie in with the theme. Which gtk theme are you using?

It's just a coincidence that I have it on the very left. Every drop-down menu exposes this. The additional condition is that it has to appear on the left edge of the screen. So if I move the firefox window so that some drop-down menu appears on the left edge of the screen, the issue is there. > I'm currently trying to reproduce using iceweasel-10, if that matters, with the > anandtech.com rss bookmarks. This is Firefox 16. gtk theme should be oxygen -- I forgot how this is set. (I use KDE4 with compositing.)

The same for thunderbird -> file -> save as. A submenu which appears (to file or template) is surrounded by the rectangle too.
Ok, I can reproduce render corruption of the popup menu when it is aligned to left-hand edge of the screen under kwin + Xrender compositing
For those following along at home, #define NO_COMPOSITE 1 in src/sna/gen3_render.c seems to be at the heart of the issue.
This is what I found locally, can you please test to see if it was indeed the same issue? commit 6c7f998f7bda4f4f1286e079412d5d3a5b2eb073 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Thu Sep 13 20:41:23 2012 +0100 sna: Fix BLT composite offset Reported-by: Jiri Slaby <jirislaby@gmail.com> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=54868 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
