940668 - Window titlebar not repainting properly after refocusing window with a modal dialog

Status: NEW

(Core :: Widget: Cocoa, defect)

Description

[Mike Conley (:mconley) (:⚙️)]

STR:

1) Open a new profile, and in Preferences, get it to load tabs from last time
2) Open up a bunch of tabs (this is optional, but helps make the bug more apparent)
3) Visit https://inventory.mozilla.org/en-US/user_systems or some other page that results in a modal dialog being spawned
4) Close the browser
5) Re-open the browser, and immediately focus another window before the browser finishes drawing
6) Once browser is opened, refocus browser window.

Result: http://people.mozilla.org/~jlin/nightly-australis-bar-white-2013-11-18.png

It might take one or two extra seconds for the browser to look like the screenshot, but it'll happen.

I assume this, like bug 939010, started on the trunk with the firefox-2013-11-18-09-41-34-mozilla-central nightly.  It'd also be interesting to know its regression range on the ux branch.
