Screen garbled in some apps when using Xinerama with Sis and Matrox cards

I am using Xinerama with two cards: builtin Sis and Matrox on PCI. In some apps (notably Thunderbird, sometimes Acrobat Reader) on right screen text is not printed and title bars are scrambled.
Right screen is Matrox card, left is Sis. I will attach screenshots and Xorg logs.
