From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Win98; en-US; 0.8) Gecko/20010215 BuildID: 2001021508 When an HTML block containing a horizontal rule (<HR>) is set in motion by incremental positioning, CPU usage gradually rises to 100%, and the time between steps gradually increases. Reproducible: Always Steps to Reproduce: Set a <div> in motion via JavaScript. Place a <HR> anywhere inside it. Actual Results: Motion gradually slows (time in between positions increases). CPU usage grows to 100%. Removing the horiz. rule eliminates the problem. If the HR is itself moved in this manner (instead of its containing div), no slowdown occurs. This has been reproduced on 3 out of 3 Win2K machines. Test pages are at: http://www.screaminweb.com/mozillatest/slowHR.html http://www.screaminweb.com/mozillatest/noHR.html

still seeing slow down on build 2001102903 win32 trunk but not really *that* noticable and CPU does not reach 100% until about half way down the page.
this seems to be fixed maybe due to the fix in bug 71979 ? Or maybe something else

WFM on Linux with Build-id:2001113006, the cpu use stays at 0% and it doesn't deccelerates when scrolling down,just scrolls cleanly.

Sory for the spam, but I'd REALLY like to know what in code caused this change in last week. It looks unbelievable that one week old Mozilla eated 100% on this and the new one only about 20%...
