Description Grzegorz Jaskiewicz 2003-11-19 18:35:01 UTC
Version:            (using KDE Devel)
Installed from:    Compiled sources
OS:          Linux

Scrolled text is resizing whole document, and eats up all CPU resource.
Page is also blinking (it should just update part that changes, but due to size changing too he redisplays everything).
Attached code shows this case.

Test case

that's still a lot of HTML. The CPU usage is acceptable here, but the
resizing is indeed a bit funny. But I guess you can provoke that bug
with other ways - and there are sure other bug reports about overhanging
content provoking scrollbars.

I just tried to strip this page to bottom, to get just this problem.
But true, this code can be made simpler with the same effect.

Cpu usage is way to high, mainly because my computer is only thin client. 
And refreshing whole page few times a second takes too much both bandwith 
and CPU to run ssh ( i am using also quite hudge key on ssh [4096] ).
But i can see on server konqy uses a bit of CPU. I have simmilar efect on 
UK's HomeOffice homepage where you have little scroll on top and i think 
www.thetube.com sometimes. 

Want me to rewrite this example, to make it more simple ? I think i can 
spend a bit of time and prepare it if is really necessary.
