385009 - Firefox doesn't show main window when pseudo-xinerama is enabled with mergedfb

Status: RESOLVED INVALID

(Firefox :: General, defect)

Description

[Alexej Davidov]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.4) Gecko/20070508 Iceweasel/2.0.0.4 (Debian-2.0.0.4-1)
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.4) Gecko/20070508 Iceweasel/2.0.0.4 (Debian-2.0.0.4-1)

This happens on a system with a Radeon R300 graphics card and the open source R300 driver.

Whenever X is started with radeon's MergedFB turned on and activated pseudo-xinerama support, firefox doesn't show the main window. Besides that, it seems to run normal. Even other startup windows are shown, like the question whether to restore the session or extension upgrade information.

If pseudo-xinerama is not activated (i.e. MergedFB in clone mode) or MergedFB is disabled alltogether, the problem does not exist. Also, it is irrelevant whether a second display is actually connected, or not.

No other application besides firefox is affected.

Reproducible: Always

Steps to Reproduce:
1. Start X with open source Radeon driver and enable pseudo-xinerama
2. Start firefox

Actual Results:  
No main window is shown

Expected Results:  
Main window

Please test with Mozilla Firefox http://www.mozilla.com Debian supports IceWeasle.

Tested with upstream release 2.0.0.4 and it works. So it seems, this problem is really Debian specific. The bug report can be closed.

This is not only a Debian-Iceweasel problem -- I have the exact same issue on Kubuntu 7.04 with Firefox 2.0.0.4.
