Status: RESOLVED DUPLICATE of bug 575184

(Firefox :: General, defect)

Description

[Christophe Calvez]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:2.0b1) Gecko/20100630 Firefox/4.0b1

When opening a new window, I can see it being drawn twice.
When it is from a not maximized window, it is drawn in the top-left of the screen, and at the right position (a bit down&right from the latest opened window).
When it is from a maximized window, it is a bit slower, it is drawn in the top-left of the screen, and a bit down&right from the latest opened window, and then it is maximized.
In both cases, the effect doesn't last, it's only a glimpse.

Reproducible: Always

Steps to Reproduce:
Open a new window (right-click, or Ctrl+N, or from File menu)



Also happens on nightly build 20100715040517 on Windows XP.
Doesn't on Firefox 3.6.6.
Happens in Safe Mode too.
