Some details on the two problems I've been having while using the text
widget (with string source):
1) Resizing with automatic word-wrap on: If lines have been wrapped
that no longer need be, much of the rest of the widget is updated
improperly.
2) When the text is scrolled or the source replaced, some of the text
is not cleared; this can result in text from the top line of the
previous source being visible, or multiple copies of text at the
top or bottom of the window that's being scrolled getting scattered
through the window. It seems to always be most of a full-height
line of text, except for the tops of the characters, at the top of
the widget, or a small slice of the text at the bottom. (Looks
like it might add up to about one character-height.) This is only
a problem with the RT server; at least, I haven't been able to
duplicate it on my QVSS server, and it happens on the Xibm server
with a VS or RT client. I've also been able to demonstrate this
problem with xedit.
