Does it happen on all Pentax pages, e.g. when you click some of the navigation links?

That's exacting my problem... I see the very same. I bet http://www.pentax.de/site/images/IS/contentcol1-bg.gif it's a 2 colors paletted Gif

I wonder why anybody uses such images for a solid color area. Can't they use CSS background-color? I would understand it for some patterned backgrounds... bz, can we consider this bug confirmed too? It may even be a duplicate. But this user reports Mac OS 10.6 and FF8. Any idea?

> bz, can we consider this bug confirmed too? Sure, what the heck. > But this user reports Mac OS 10.6 and FF8. Any idea? Nope. Worksforme on 10.6....

Confirmed by the author of bug 689962 of which this may be a duplicate. Pipe, could you read the description here and all the settings the reporter posted. Can you see something your system has in common with his one? Like graphics card?

Nope, my graphic card info is this: Modelo de chipset: NVIDIA GeForce 9400M Tipo: Pantalla Bus: PCI VRAM (total): 256 MB Fabricante: NVIDIA (0x10de) ID del dispositivo: 0x0863 ID de la revisión: 0x00b1 Revisión de la ROM: 3448 Versión gMux: 1.8.8 Computer: Nombre del modelo: MacBook Pro Identificador del modelo: MacBookPro5,3 Nombre del procesador: Intel Core 2 Duo Velocidad del procesador: 2.66 GHz And the OSX 10.5.8

(In reply to aceman from comment #1) > Does it happen on all Pentax pages, e.g. when you click some of the > navigation links? OK, I clicked around. It happens on all pages exept the start page: http://www.pentax.de/de/foto.php

Good, that one seems to not contain the supposedly problematic background image http://www.pentax.de/site/images/IS/contentcol1-bg.gif .

Can you confirm if this is still an issue on latest nightly? I can't reproduce this locally on OS X 10.7
