Description Helge Hielscher 2002-09-30 16:20:13 UTC
Version:            (using KDE KDE 3.0.3)
Installed from:    Mandrake RPMs
OS:          Linux

When you load a large image, the CPU load goes to 100% (with X at about 70%), even if Konqueror is minimized. I am using a Duron800 (384MB Ram) with a 32MB Nvidia Graphics Card (nvidia driver).
The same images loaded much faster using mozilla.

Here a some links to large images:

I can confirm the Behaviour of Konqueror with KDE 2.2.2 <br>
I happens, when view ist set to "embedded Picture-Viever", <br>
which ist the Standard-Setting. <br>

konqi also eats all available memory until OOM-killer arrives. (I've tested machines 
with 128MB and 256MB memory). I'd say this is a showstopper. 
Comment 3 Patrick Valsecchi 2002-12-17 02:33:07 UTC
Same behaviour here with KDE 3.1rc5. Does it when it's a local file as well. 
I have a Celeron 500 with a Matrox G400.

Loading the URL below causes serious problems (system slows to a crawl, mostly
virtual memory I think; high CPU) in Konqueror because of the large image.

DO NOT OPEN THIS IN KONQUEROR UNLESS YOU WANT TO RISK A SYSTEM FREEZE

Also the image is stretched out of proportion.

Using KDE 3.1.

I can also confirm this same problem. They seem to be very slow, and 
some are completely skewed. I'm on 3.1.1

the same especially if you refresh the page :
http://linux-wizard.tuxfamily.org/bugs/test4.html
http://linux-wizard.tuxfamily.org/bugs/images/MarPers2.jpg

this happen also for local view ( put the image on the disk, double click to preview and then hit refresh several times ).

even an AMD Athlon 1900+ with 512M RAM will be down at the end.
