Hello! I had the same problem too, but not only with iceweasel. With iceweasel 3.5.8 the boxes where black, with version 3.5.12 I had grey boxes, then also galeon and revelation were showing grey boxes.
After some investigations I found that it must have something to do with the fglrx drivers. X-org without using them does not have this problem! (only commented the drive in xorg.conf for my ATI 5770) I am using Debian unstable 64-bit (last update 09/15/2010): ii fglrx-amdcccle 1:9-10-1 control panel for the non-free AMD/ATI r6xx - r7xx display driver (dummy) ii fglrx-atieventsd 1:10-8-1 external events daemon for the non-free AMD/ATI r6xx - r7xx display driver ii fglrx-control 1:10-8-1 control panel for the non-free AMD/ATI r5xx, r6xx, r7xx display driver ii fglrx-driver 1:10-8-1 non-free AMD/ATI r6xx - r7xx display driver ii fglrx-glx 1:10-8-1 proprietary libGL for the non-free AMD/ATI r6xx - r7xx display driver ii fglrx-glx-ia32 1:10-8-1 proprietary libGL for the non-free AMD/ATI display driver (ia32 libs) ii fglrx-kernel-2.6.32-5-amd64 1:10-8-1+2.6.32-21 ATI binary kernel module for Linux 2.6.32-5-amd64 best, -harti -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
