222475 - window jumps up and down a few lines at a high speed

Status: RESOLVED DUPLICATE of bug 219643

(SeaMonkey :: General, defect)

Description

[johannesg]

User-Agent:       Mozilla/5.0 (Windows; U; Win 9x 4.90; en-US; rv:1.4) Gecko/20030624
Build Identifier: http://ftp.mozilla.org/pub/mozilla.org/mozilla/releases/mozilla1.5/mozilla-win32-1.5-installer.exe

After opening a page or image (either by starting the browser from scratch, or
on a new tab, or in a new window) the content-part of the window will rapidly
jump up and down by a couple of scanlines (this appears to happen at the maximum
speed my hardware is capable of). I have reproduced this with locally loaded
images as well as various websites. The problem occurs about 75% of the time I
load a page or image, and sometimes goes away after I hit reload. The only part
that is jumping is the actual "content", the window around it is rocksolid. The
effect stops temporarily when I "grab" the window border and resize it slightly.
It continues when I release the border.

I have seen the problem in both Mozilla 1.5rc2 and Mozilla 1.5. I have not seen
it in Mozilla 1.4. OS is Windows ME.



Reproducible: Sometimes

Steps to Reproduce:
1. Start Mozilla 1.5.
2. Open any page or image. The problem occurs occasionally.

Actual Results:  
Page jumps up or down.

Expected Results:  
Not jump up or down. This gives me a headache.

Theme is "modern". I have not tested with the default theme.
