Does anybody know of any workaround to the dreadful

I am talking about the bug whereby, you'll be typing
away above a chunk of text when suddenly you will
start typing over the text that is underneath - the
text at the bottom of the text view doesn't get
redrawn, in other words. This happens in Text Edit and
Xcode loads. It was present on Panther, too, but I
only ever saw it in rare circumstances; on Tiger it
happens all the time, I don't know why.
If this is the same bug I'm thinking of, then it's an NSView
redisplay issue, and a fix is currently in testing. In the meantime,
a workaround for users is to select all or otherwise force
redisplay. A programmatic workaround would be to force display of
the entire visible rect, but I would hesitate to add such a
workaround to an application; this really should be fixed in the AppKit.
