Status: RESOLVED DUPLICATE of bug 545892

(Core :: Widget: Win32, defect)

Description

[Joel A. Villarreal Bertoldi]

User-Agent:       Mozilla/5.0 (Windows; Windows NT 6.1; en-US; rv:2.0b2pre) Gecko/20100714 Minefield/4.0b2pre
Build Identifier: Mozilla/5.0 (Windows; Windows NT 6.1; en-US; rv:2.0b2pre) Gecko/20100714 Minefield/4.0b2pre

While using Minefiled, a redraw event triggered, rendering the title bar unreadable and the title bar. Minimized all the windows and then noticed that the window composition is also incorrect.

Problem is probably related to Windows 7's desktop composition feature.

Reproducible: Sometimes

Steps to Reproduce:
1. Have NetBeans or any Java-based application or any other software that uses a customized window skin (for example, the Adobe suite) or Windows Live Messenger.
2. Use Minefield.


Actual Results:  
On a redraw event, title bar background gets mixed up with other windows behind Minefield window.

Expected Results:  
Title bar and tabs should be opaque.

No customized skins have been used.
