Subject: 26.1; Blank help-echo tooltips for mode line menus
Date: Tue, 12 Mar 2019 12:45:58 +1300

Following from:
https://lists.gnu.org/archive/html/emacs-devel/2019-03/msg00324.html

Recipe from emacs -Q (and --with-x-toolkit=lucid)

* M-x text-mode
* Mouse 1 click on "Text" in the mode line to open the menu
* Hover over any of the menu items until the tooltip appears

For me, this produces tooltips of the appropriate dimensions, but the
text itself is not visible.

When I use the top menu bar instead of the mode line, the tooltip text
is visible.

I note also that if I simply hover over "Text" in the mode line, the
"Major mode" tooltip appears with visible text; however if I click-and-
hold the mouse button *before* the tooltip has had time to appear, then
it will be blank when it does appear (over the top of the menu).

Thanks for testing.  I've pushed the patch to master as 82d6b390b5e
(flush_frame part) and 4a5a74a07ff (inhibit-double-buffering part).
