This bug is related to the mode-line erasure problem I mentioned in
http://lists.gnu.org/archive/html/emacs-devel/2015-01/msg01040.html .
To reproduce the problem by the instruction below, you would need to
make sure that your X11 compositing manager is turned off. I tested
on Cent OS 5.11, default setting. See also
http://lists.gnu.org/archive/html/emacs-devel/2013-04/msg00600.html .
Steps to reproduce:
1. Create a file (say, ~/test.el) containing the following contents:
(custom-set-faces
'(mode-line ((((class color) (min-colors 88)) (:background
"grey75" :foreground "black" :box (:line-width 2 :color
"grey75" :style released-button)))))
)
2. $ emacs -Q -D -l ~/test.el
3. C-x 2 C-x 2 C-x 2
4. C-x o C-x o C-x o
5. Move another window (e.g., the terminal window from which Emacs is
invoked) so that it hovers over the Emacs frame.
Result:
The upper two mode-lines among four are not redrawn after their hidden
part is revealed (see the attachment). They are not redrawn in
response to expose events because the flag `enabled_p' for these
mode-line glyph rows have been set to false.
