Package: firefox
Version: 1.5.dfsg+1.5.0.4-1
Severity: normal
all gecko-based browsers I have tried (firefox, epiphany-browser in amd64 and
mozilla-browser in an ia32 chroot on an amd64 system) do not seam to
update the complete page when scrolling a page containing a
position:fixed element when a composite manager is running. the result
is that the fixed element "lags" over the rest of the page. for a
screenshot of this, see http://zombiehq.xyzplanet.net/~thomas/ff_pfixed_lag.png
For example, this happens with the HTML
<html><body><script language="javascript">
for(var i = 0; i < 2000; ++i) document.write("text "); // script for brevity
</script><div style="position:fixed;top:0;background:grey">
this text lags when scrolling
</div></body></html>
I use the proprietary nvidia drivers for compositing. As
composite/window managers I have tried xcompmgr on xfwm4 and metacity
and xfwm4 with its own compositor.
This does not occur in Konqueror or when multiple fixed elements are
present.
