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. Steve Berman
