Status: RESOLVED DUPLICATE of bug 429698

(Firefox :: General, defect)

Description

[Jeremy Visser]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.3) Gecko/2008100814 Gentoo Firefox/3.0.3
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.3) Gecko/2008100814 Gentoo Firefox/3.0.3

The autoscrolling popup (the little bubble that comes up when you middle-click on a page) was revamped to be alpha-blended in Firefox 3, so it appears semi-transparent and antialiased. This works fine on Windows and Mac OS X.

However, on Linux, it is still the ugly non-transparent and aliased popup from previous Firefox releases. This is unacceptable, as many Linux users are now running composited desktop environments with full support for ARGB windows.

For proof that X11 supports ARGB, install Ubuntu 8.10, make sure Compiz is running, enable the "dark" theme that ships with it, and open an ARGB-enabled application such as System Monitor. You will notice that the window body is slightly transparent.

Reproducible: Always
