    I assume that you are referring to the remainder of the Firefox logo on the right side. The first question is whether you see this in other applications or only in Ff? I am going to assume the latter.

    I suspect that the problem is somewhere in your Firefox configuration files. I am not an expert in this area, but I can tell you that your firefox configuration is found in /home/name/.mozilla/firefox. There is a file called profiles.ini (in English, I don't know what it is called in Russian), which does not appear to have anything significant in it. There is a directory with a name made up of random characters followed by ".default" (or the Russian equivalent). It contains (among MANY other things), a directory called "chrome" (in English). This directory contains two *.css files which contain the basic configuration information. In (much) earlier editions of Firefox, it was possible to manipulate the contents of this file by editing an extended version of the preference dialog which was in the form of a table. But I can no longer find the interface to that dialog. You may be forced to edit the css files, by hand. This could make Firefox unusable, (there are warnings to that effect), so please be careful.

      The artefact - is a gray stripe in window header (wich should be totally blue). And I saw this bug many times in different applications. It usually appears when switching between windows.

        I see the same problem from time to time. It's some problem with compositing because when I turn compositing off it doesn't happen anymore. Moving the window or hovering over the title bar makes it go away. What video card do you have? Mine is:

        Code:
        tnorris@tnorris-laptop:~$ lspci | grep -i vga
        00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c)
        tnorris@tnorris-laptop:~$
