Description Alexandre Racine 2009-05-04 05:50:13 UTC 
Version:           0.10.0 (using 4.2.2 (KDE 4.2.2), Kubuntu packages)
Compiler:          cc
OS:                Linux (x86_64) release 2.6.28-11-generic

Going from image 1 to 2, 2 to 1, multiple times does weird results.

It seems like there is a printing problem.

See attached files. You can see on capture-B that I can simply drag anything and reveld the image!

Never see this dysfunction on my computers sound like a cache problem...

How many ram do you have ?

Comment 4 Marcel Wiesweg 2009-05-04 18:03:59 UTC 
Maybe a missing call to viewport()->update() together with Qt redrawing very conservatively?
What is your Qt version? Your graphics driver?
Comment 5 Alexandre Racine 2009-05-05 01:28:58 UTC 
Gilles : 4GB RAM, video card is a GeForce 8800 GT with 512MB RAM.

Marcel : qtconfig tells me 4.5.0 and nvidia driver 180.44.
Comment 6 Alexandre Racine 2009-05-17 16:58:28 UTC 
Additional note : I have been using it for a while now and tt only does this when going to the first picture or when going to the last picture. This would confirm that it is not a memory bug.
Comment 7 Alexandre Racine 2009-05-28 03:13:39 UTC 
Additional stuff :

On my comment above. It mostly do so with the first and last picture, but it did it on some occasion with other pictures.


Nevertheless, I have found a way to make this bug happen more frequently. Look at a picture, open a pannel, let's say the meta-data one, and clic on the arrow right, right, right a couple of times and sometime the next picture does not load. Clicking anywhere will make it visible correctly.

Alexandre,

Can you check again using digiKam 1.0.0-beta1 ?

It seems ok, but I am testing this with another machine. If 1.0 makes it to the next ubuntu 9.10 official and this is still here, I'll reopen.
