Chris - you may recall that last week, I bisected the problem I am getting to:

 ec0866e86d365ae3fd9790b1b263d49fc4981220 is the first bad commit
commit ec0866e86d365ae3fd9790b1b263d49fc4981220

     sna/glyphs: Fix computation of extents for long strings


See http://lists.freedesktop.org/archives/xorg/2013-October/056141.html.

I reported that the commit did not revert cleanly against the current HEAD. You
reported that there had been a fix to that patch, but unfortunately, it didn't
dawn on me that reverting the fix first would be the right thing to try.
However, in a flash of inspiration, that idea came to me this morning.

So, using the tarball up to and including
93193aaf7d0fc4e3a3b9be1632bfd36331b47d2e, which was head earlier this morning,
I've reverted yesterday's test patch, the fix
(f81a7f7192a821654bc72a6b34625a6367cb8479) and the patch I reached in the
bisect (ec0866e86d365ae3fd9790b1b263d49fc4981220) and built the driver.

That driver improves things somewhat. I still get some corruption, but it's now
wholly contained within the content area of the window - i.e. it does not stray
into the status bar or outside the window into other windows lower in the
stack.

I'll attach a snapshot in a few moments.
