Initial Comment:
I was editing a file over SFTP today and sometimes random text would be inserted near the top of the file. I couldn't tell if this text was from the clipboard or from other parts of the file. Undo did not remove the random text, which suggests its a bug in the low level JEditBuffer code.

I think that some time ago I have seen a similar behaviour which appeared
only when "quick copy" was activated. Unfortunately I can't find the note
I made then. It was caused by some specific mouse movement, IRC. I don't
know if the text was undoable because I usually noticed it only much
later, so undoing would have meant losing everything I'd typed in the
meantime. I was not using SFTP, though.

I've also seen a repaint glitch like the one Marcelo describes. So far I
could not reproduce it deliberately. When it happens, the first 5 columns
(or so) of some lines are overwritten with garbage. White space is
preserved, IRC. It usually goes away after some scrolling.

Do you have any hint to reproduce that ?
In fact it happened sometimes last year but randomly and I was never able
to reproduce that.
It doesn't happens anymore for me.
What I found is that it happened when I paste text from clipboard, the
text was pasted at cursor position but also in the beginning of the
buffer.

Actual text was inserted; I noticed the problem after saving the HTML file
and viewing it in a browser.

Hi Slava,

Was it actual text being inserted, or did it look like a painting problem?
I've been seeing things that look like this some times, but saving the
buffer (which seems to cause a repaint of the whole buffer) gets rid of
the garbage. Still annoying though.
