Produced using nightly 2000111521 under Linux. When scrolling using mouse, it is very very slow. I also tried NS6 on win32 and it is very very fast.
WIN2k build 2000111404 I can´t use my mouse to scroll it this form ! I always scroll the page !
This is a dupe but I can not find it. :-(
Summary: when scrolling in the form text field using mouse, it is VERY slow → [DUP]when scrolling in the form text field using mouse, it is VERY slow
seems to scroll OK for me, linux build 2000-12-05-08
I'm confirming this bug as a) it's certainly slower than it should be b) I can't see any dups that relates to textareas. Basically, if I drag the textarea's scrollbar it does seem to jerk the display... gkrellm indicates that during the update cpu shoots to 100% usage. What I would expect is perfectly smooth scrolling, but I guess we haven't seen this problem before because this example uses a lot of text. My machine: K6-2 300, Debian Woody, XF4.0.1, 256Mb RAM, mozilla 2000120808. Adding perf keyword and updating summary.

Status update: This page WFM on 2002050504 win32 on win2kpro.
WFM Linux/2002051507; seems fixed
WFM with Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.0.0+) Gecko/20020531 and RC3 Please have a look on bug 100951 ! Any problmes seen (with other OS) to set this bug FIXED or WFM? Can we close this bug ? keywords --> qawanted ?
The nsBlockFrame.cpp and nsBox.cpp changes in 141900 fix a problem where scrollbars were causing things outside of textareas to reflow. That is reflow commands generated by setting attributes on the scrollbar, or dragging the scrollbar slider were being propogated up the parent frame hierarchy. An example of a page that had terrible scrolling performance prior to the checkins for bug 141900 is: http://www.wikipedia.com/wiki/September_11,_2001_Terrorist_Attack/New_York_Times_stories&action=edit I'm going to assume that the problem reported here was the same thing. Please reopen if it still happens in a trunk build from 06/14/02 8am or later.
