717091 - [Azure] App tabs turn transparent when title changes

Status: RESOLVED DUPLICATE of bug 736460

(Core :: Graphics, defect)

Description

[Bobby Johnson [:rjohnson19]]

Mozilla/5.0 (Windows NT 6.1; WOW64; rv:12.0a1) Gecko/20120110 Firefox/12.0a1

With gfx.content.azure.enabled set to true, App tabs that normally 
'light up' blue when the title changes turn transparent instead.

Steps to Reproduce:
1. Create gfx.content.azure.enabled and set it to true in about:config and restart.
2. Pin as App Tab a tab that updates continually such as Twitter or Google Reader.
3. Wait for the pinned tab to update.

Actual Results:
App Tab background turns transparent (aero glass).

Expected Results:
App Tab has blue highlight like without Azure enabled.

This now works for me with
Mozilla/5.0 (Windows NT 6.1; WOW64; rv:13.0a1) Gecko/13.0a1 Firefox/13.0a1 ID:20120218031156

Attachment: Testcase (constantly changing page title)

After double checking in a new profile, my report of 'works for me' was premature.

This still happens in a new profile, and after resetting preferences in my default profile.

This testcase just perpetually changes the window title, so you can make it into an app tab to more easily see the issue.

Thanks a lot for the testcase here, having said that, I can't reproduce the issue! Any chance you could add a screenshot so I know what to look for?

The top of the image has a screenshot of what I'm seeing with Azure enabled, and below it, the same situation (an 'active' app tab) without Azure enabled, for reference.

Can you still reproduce this on current builds? I can't.

Yes, I still see this. But if I'm the only one who can see this rather subtle issue, its probably specific to my graphics card / drivers, and perhaps should just be closed out.

Let's not close this bug but leave it open, I probably just won't let it block enabling by default.
