On the specified page the text is moving (better: shaking), probably depending
on action-smileys. Mozilla 1.0.1 has no problems as well as IE.
Just watch the given page a while with Mozilla in default size!
Resizing to other sizes removes the behaviour!

Reproducible: Always

Steps to Reproduce:
1.Leave Mozilla in default size
2.Goto above link
3.watch the text parts moving/shaking

Actual Results:  
Text was moving/shaking

Expected Results:  
Display non-moving text
Lutz,  what is your "Display resolution" preference set to?
(under Preferences->Appearance->Fonts),  I'm guessing "System setting" - 
in that case, please run the "xdpyinfo" command in a shell window and report
the value it prints for "resolution".  Finally, if you change the Mozilla
preference "Display resolution" to "96 dpi" and then *restart Mozilla* does
the "shaking" stop after that?

I see this with the testcase, and I've been seeing it when selecting text on
tinderbox.  116dpi.
Pending answer from Reporter - it's a dupe of bug 215341
(It only occurs when system dpi != 96)
I suspect this is a rounding problem of some sort combined with the fact that
we're unioning all the invalidate rects.
Preferences - Apperarance - Fonts is set to "System Setting",
xpdyinfo resolution is 90 x 89 dots per inch.

When setting to 96 dpi its gone as proposed.
Thank you.
