Do you have extension installed ?

I see something like this too, Mac OS X 10.5.8. Started only a couple of days ago at most (Tbird 3.1.8 beta) and only happens on text/plain mail (which is the bulk of my mail, e.g. bugzilla spam). When I use the arrow keys to scroll there are subtle artifacts, using the scroll bar makes it really smear. When I unchecked the "use fixed width font for plain text" option the problem went away. When I re-checked that option it seems to have stayed OK so far, hasn't come back.

Well, the "fix"/workaround didn't last long. A few hours later and again I'm getting smeared text as I scroll in plain text mail.

This sounds really likely to be a (mozilla) platform issue, although I could believe we are doing something unique that causes layout to perceive our bounding box as a pixel or two different from what it otherwise is so that any fastpath blitting causes smearing... If you do things that should cause a repaint from first principles (presumably resizing the window or moving a splitter), I assume everything instantly goes back to crisp?

spr, dveditz, do you still see this? To quote from comment 4 ... If you do things that should cause a repaint from first principles (presumably resizing the window or moving a splitter), I assume everything instantly goes back to crisp?
