1002813 - Form observer popups don't show up on Linux

Status: RESOLVED DUPLICATE of bug 994562

(Core :: Widget: Gtk, defect)

Description

[Bill McCloskey [inactive unless it's an emergency] (:billm)]

Attachment: test.html

I'm not sure where to file this. However, the problem is that entering illegal form data doesn't show a popup in Linux. I've attached a testcase. You should be able to hit enter and a popup will show up telling you that the entered data is illegal. This is what happens on a Mac.

On Linux, there's sometimes a brief flash of black near where the popup should appear. Otherwise nothing happens. I've traced through the code, and we are showing the window for the popup. We're not hiding it until the user clicks away. I also don't see any calls to SetFocus that might cause the window to be lowered.

I can reproduce when using a non-compositing window manager.
The same bug occurs on the doorhanger from padlock by the URL.

The regression trigger may be the introduction of animation for the doorhangers, but it would be worth confirming.
