After seeing the problem Nick Roberts reported in the thread
"Flickering mouse-face" also in my patched Emacs, I did further
experimenting and did observe the milder form of incremental undrawing
with the patch. I also have a somewhat unstable recipe for
reproducing it. Currently, I see the problem with the following shows
(using the patch to xdisp.c applied in revision 1.1137):
1. emacs -Q
2. M-: (setq gnus-select-method '(nntp "news.gmane.org")) RET
3. M-x gnus RET
4. S s gmane.emacs.devel
5. Press RET on this group and at the prompt "How many articless from
gmane.emacs.devel (default 64519):" type 1000 RET
NB: The rest of this recipe depends on the top line in the Gnus
Summary buffer being this:
. [ 273: Lennart Borgman ] File name completion in *Shell* on w32
6. Put the mouse pointer between `[' and `]' on this line, so that
mouse-face highlighting is displayed.
7. Type `C-s 1 5 l :' and the C-g. Now you will see mouse-face
highlighting in the first also in the space between `]' and `F', and
when you mouse the mouse pointer, that space still shows mouse-face.
Given this problem and the new problem reported by Nick Roberts, it
seems this patch is insufficient.
