Description

Attachment: screenshot

Browser window isn't drawing properly in the background on OS X 10.8.

This is a very new regression on mozilla-central, hasn't hit Nightly builds yet.

Does it make a difference if the app itself is in the foreground or background?

Is putting a window into the background (by making some other window the foreground window) enough to make the bug happen?

Are you testing with a "published" build, or just with a build you made yourself from current trunk code?

I can actually reproduce this with the currently Nightly. I think I was accidentally testing with Aurora before.

All I have to do is start the browser then click on the desktop.

I can reproduce in try builds, the current nightly, and my own custom builds.

Just tried with today's mozilla-central nightly on OS X 10.8 and couldn't repro.  I tested on a Retina MBP that's about a month old.

By any chance does this happen with other programs (like Safari)?  Does it go away if you restart your computer?

Oops, just looked more closely at your screenshot.  I *can* repro, on both 10.8 and 10.7.4.

For the record, the problem is that the titlebar and the rest of the toolbar are different shades of grey when the window is in the background.

This may be related to (or a dup of) bug 766106.

This is a recent regression on OS X 10.6.8, 10.7.4 and 10.8.  So it's unrelated to bug 766106.

Here's the regression range:

firefox-2012-08-13-03-05-32-mozilla-central
firefox-2012-08-14-03-05-21-mozilla-central
