Bug Description
Binary package hint: xorg
Since the libdrm fix (619663?) was downloaded to my laptop yesterday, I switched my monitor config from top/bottom to side-by-side. It appears that if I have the secondary display enabled, I now end up with corrupted text in emacs, my primary editor. I can reproduce the corrupted text when I do a mouse selection (as shown in the pictures I will attach). I can also see corrupted text when I type, or when I paste text into the buffer. If I disable the second monitor, I can't reproduce the problem.
I haven't seen the problem in other applications yet, so maybe this is an emacs issue instead.

I should note some further observations:
First of all, see the word "software" in the second line for the 'Mouse selection' picture. This example is actually quite tame. I really can't see what I'm typing properly most of the time. In fact, the last line in the picture (should be the same as the line above it) attached to this comment is the norm.
When I press enter, or when I do things that appear to cause a redraw, normal text returns.
I've seen blinking, outlined, and bold text appear, and not directly under the cursor while typing. Underscores have ended up in odd places.
I did test putting my secondary monitor under my laptop monitor, and I could not reproduce the problem. This also makes me think that this is related to the libdrm framebuffer fixes that came in this week.
