Description Yves Glodt 2003-04-13 19:48:11 UTC

Version:            (using KDE KDE 3.1)
Installed from:    Unlisted Binary Package

Hi,

(after a 5 min fight with the wizard I eventually arrived here... grmbl)


I found 2 problems with gif images, and I file them in one bug as both are gif handling issues.

First, this animated image:
http://www.mind.lu/~yg/shared/santa_en_apuros.gif (48kB)
is using 100%cpu on my Athlon 2200 while being displayed in konq, and I think
this is not normal.

Second, this image:
http://www.mind.lu/~yg/shared/plan.gif (1.8MB)
takes approx 1 minute to load in konq with cpuload jumping around like crazy, and big mem and eventually filling 80% of my 256 MB swap (I have 256 MB RAM)
Once loaded it shows correctly.

I use 3.1-rc from texstars rpms (with qt3.1.1, idem texstar).

regards,
yg

I get very slow loading and large memory usage also when using konqueror to 
view large JPEGs and GIFs.  Example: 
http://www.famousbabes.com/pics119/elishaC/elishaC018.jpg - takes over a 
minute to load on my system (PIII-450, 384MB RAM, TNT2-16MB).  Most of the CPU 
usage seems to be in XFree86 (version 4.2.0), but Mozilla (for example) loads 
the image very quickly. 
 
Possibly this is related to Bug 55643 - KDE allocating pixmaps the size of the 
image.  And Bug 29420 - which relates to large JPEGs taking up massive amounts 
of RAM on Konqueror embedded.

I can confirm, actually opening a dozen large jpg/png/gif images in own tabs each is 
one of the very rare cases where I can significantly slow down the GUI response within 
KDE on a AthlonXP 2000+, 768MB RAM, GF2MT even after loading. This is pretty 
amazing considering the same pictures embedded in html pages work smooth 
(serious problem with kpart for pictures?).
