144440 - Render errors with modern theme in some 24/32-bit color resolutions

Status: RESOLVED DUPLICATE of bug 138472

(Core :: XUL, defect)

Description

[Martin Wulffeld]

BuildID:    Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.0rc2)
Gecko/20020510

With 1.0RC1 and 1.0RC2 in Windows XP I have seen strange render errors mainly in
the URL bar just around the baseline of the URL text. The error seems only to
occur when the Modern theme is applied and in resolutions 1152x864 or higher
with 24-bit or 32-bit color. I don't see the problem with 16-bit color.

Reproducible: Always
Steps to Reproduce:
1. Apply Modern theme and restart Mozilla.
2. Switch to a 1152x864 or higher resolution with 24 or 32-bit color. 
3. If the error doesn't show immediately try resizing the window slowly one
pixel at a time. That should do it.

moment.
