Subject: 23.0.91; flashing/slow highlighting
Date: Tue, 17 Mar 2009 15:53:00 -0400

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug <at> gnu.org mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

Put the following in a buffer and `M-x compilation-mode'.  Then hover
the mouse over the beginning of any line.  The text highlighting sweeps
visibly slowly across from left to right; it actually appears to be
happening twice for every line.  Regardless, it's way too slow.  This is
a recent snapshot on MacOSX.

Works fine for me on GNU/Linux.

Me too, of course.  I was reporting a platform-specific problem.

Which is exactly the point of my message, to allow this to be classified
as a platform-specific problem :-)

Thanks for clarifying.  Next time I know that to be the case I'll be  
sure to note it in the report.

On GNU/Linux I experiences flashes/slow highlighting too, (with
flyspell) but I wasn't able to reproduce this specific case. I don't
think it's a platform-specific problem, but rather a performance
problem.
