Re: mouse-face redisplay messy on Windows XP x64 Edition
I can reproduce similar results with M-x shell on GNU/Linux following your description (terminating each multi-line with C-j is crusial!!) It looks like redisplay fails to delete to end of line when lines have mouse face. Is it really a bug in Emacs, or is this just a matter of how to implement output of CR into the comint buffer? If it is a real bug, can you fix it? ___ emacs-pretest-bug mailing list emacs-pretest-bug@gnu.org http://lists.gnu.org/mailman/listinfo/emacs-pretest-bug

If it is a real bug, can you fix it? I think it's really a bug, but it's difficult to fix: basically CR in comint currently erases line and puts point at BOL, but it should only put point at BOL (and then overwrite the line when subsequent output comes). Problem is that comint's normal behavior is not to overwrite text but to insert it, so it's not trivial to change. Maybe we could try to special case the situation where CR is immediately followed by LF?

In a Gnus Summary buffer, mouse-wheel scrolling up and down over Author's names causes fragments of the highlight mouse-face to remain after the mouse cursor has left them. Here's an example screenshot: http://www.shootybangbang.com/redisplay-mouse-face-bug.png I've seen the same thing on W32 on recent CVS checkout over the last month or so (current version: GNU Emacs 22.0.50.1 (i386-mingw-nt5.1.2600) of 2006-09-30, but I had seen it on a 2006-09-04 checkout as well).

It looks like redisplay fails to delete to end of line when lines have mouse face. I've never seen the original small artifacts problem on GNU/Linux though. But I usually have mouse-highlight set to 1, which may easily hide this problem. I don't have time to dig into it right now, but this is a corner case which should not delay the release. -- Kim F.
