Also, while I'm moving the scrollbar my CPU usage jumps to 100%. Obviously Moz is having to do some extra work to render as it scrolls. Internet Exploder 5.5 scrolls the page with no trouble. Reproducible: Always Steps to Reproduce: 1. Go to the site. 2. Drag the vertical scrollbar up and down. Actual Results: Jerky scrolling, 100% CPU load. Expected Results: Smooth scrolling, low CPU load. My CPU is a P4-1700.
With 2002102208 on Win2k scrolling is smooth on my Athlon-600. Only at the very top it is not perfectly smooth. Don't know if I would have recognized it without looking for it... Maybe graphics card/driver related? Mine is a TNT2.
OK. I updated my display driver, and the problem has disappeared. Thanks for the tip, and sorry to bother you! Andrew.
Fine! Now you probably can resolve this bug as INVALID, which means that it is not a bug in mozilla. If you think so.
This was a problem with my display driver, not with Moz. Moz rules!
verified. However, the slow scrolling problem DOES exist for huge vertical images (say, 1 pixel wide and 4000 pixels high). We have that bug filed and are working on it.
