Description

7 years ago
User-Agent:       Mozilla/5.0 (Windows NT 5.1; rv:2.0b7) Gecko/20100101 Firefox/4.0b7
Build Identifier: Mozilla/5.0 (Windows NT 5.1; rv:2.0b7) Gecko/20100101 Firefox/4.0b7

When all FF windows minimized and I summoning MS Windows XP Security Dialog and switching back and trying to open new FF window results in new window is blank (black) and all attempts to open any new FF window results in same problem. When trying to restore first (minimized) FF window it is blank too but has white color. Only restart of FF have effect.

Reproducible: Always

Steps to Reproduce:
1. Run FF 4.0b7 on MS Windows XP SP3 (FF have about:blank page by default)
2. Open any usual www-page
3. Minimize FF window
4. Press Ctrl+Alt+Del to summon Security Dialog
5. Press Esc to return to desktop
6. Run another FF instance

Actual Results:  
Now you have black area instead of about:blank page and you'll see similar problem on first instance of FF when try to restore minimized window

Expected Results:  
First instance must show web-page opened early. Second instance (window) must show about:blank page.
Do you have an intel graphic card (bug 604647) ?
Please post the graphic section from about:support

No, it is nVidia GeForce 6600:

Graphics

Videocard Description: NVIDIA GeForce 6600 
manufacturer ID: 10de
device ID: 0141
video memory volume: Unknown (really: 256 MB)

Problem appears only when all FF windows minimized, and after switching to/from Windows "Security Dialog" I trying to open new window before restoring early minimized. 

Bug is only in FF 4.0 beta. FF 3.6.11 works fine.

Does disabling Hardware Acceleration (resp. setting layers.accelerate-none to true in your Case) help?
How about updating the Graphics Driver and re-test?

Yes, disabling Hardware Acceleration by setting layers.accelerate-none to
"true" helps.
Updating graphics drivers to latest (ver 6.14.12.6099) has no effect.
Eugene, does this happen with the latest nightly on your machine? http://nightly.mozilla.org/
