[Hardware] Изменение разрешения на лету.

Вот наконец-то запустил 3d-ускорение на radeon`е 9600(тупо скачал,собрал
и поставил из сизифа kernel-modules-fglrx-std26-up и fglrx_glx), всё
вроде нормально, но заметил одну странность, если запустить приложение
для которого необходимо разрешение меньше выставленного, то вместо
выставления такого разрешения, появляется чёрная окантовка, на
radeon`е(драйвер) всё работало, это фича или бага?
Система: АЛМ2.4 2.6.8-std26-up-alt9
Железо: radeon9600, nforce2 ultra 400, lcd monitor с DVI подключением.
