OK. I have tested extensively the problem. To summarize up, my though: The problem exist only in gtk 2.8.x, I assume that this version (2.8.x) depend on cairo, which corresponds to accelerate rendering, and in version 2.6.x there was no cairo. (If Im wrong correct me).
So the bug is either in gtk or in cairo or in xorg or in nvidia propriatary driver. I have tested this bug with "nv" driver too. The bug does not appear with the "nv" driver (included in xorg 6.8.2). But the external vga does not work (so I must use the propriatary driver). With the propriatary nvidia driver (version 1.0.7474, installed from nvidia-kernel-source) the bug appear only, when I enable the following option: Option "RenderAccel" "true" (So I have commented out, and it works now. Just my windows are somewhat slowish) Due a bug in nvidia driver I must load the nvidia module with the following option (to not have 5 centimeter black bar on my laptop screen. My resolution is 1280x800): NVreg_SoftEDIDs=0 NVreg_Mobile=0 I have found in the nvidia driver (version 1.0-8178) changelog the following: ,,Fixed a corruption bug with RenderAccel and the Composite X extension when using wide desktops.'' Maybe this bug is fixed in this version (I use RenderAccel and I have wide screen too). I think its time to install a new 2.6.15.1 kernel with the newest nvidia driver. To summarize, I dont think its a bug in the debian packaging rather in cairo/nvidia driver. So I will install the new nvidia driver, and report the bug either against cairo and nvidia propriatary driver ([EMAIL PROTECTED]). Thx for the hint Sebastian.
