I was playing with these SVG demos and noticed a draw glitch with http://www.croczilla.com/svg/samples/xbl-shapes2/xbl-shapes2.xml .
It doesn't happen with FF 3.0.6.

Reproducible: Always

Steps to Reproduce:
1.  Open http://www.croczilla.com/svg/samples/xbl-shapes2/xbl-shapes2.xml
2.  Click on the top right control point of the spline curve and slowly drag it downwards, then back up.
3.  Watch for redrawing glitches.
Actual Results:  
Moving downwards, at some point the top of the curve does not correctly erase its previous location, leaving a glitch on the screen.  Moving upwards, at some point the top of the curve does not render completely.

Expected Results:  
No rendering glitches.

It's possible there's a bug in the sample SVG, CSS, or XBL, but I can't reproduce the glitch in Firefox 3.0.6.

I was able to reproduce it but only one time.

This should be fixed on trunk with the landing of bug 493079

I did see this before too but bug 493079 does seem to have fixed it.
