I have a Laptop with two graphic cards. When I switch from power saving mode, which uses the "Mobile Intel(R) 4 Series Express Chipset Family" to the normal mode with a "ATI Mobility Radeon HD 4330", the GUI elements partially freeze or the website starts to to repeat itself (See link). After Switching back to the Intel graphics it works again. It doesn't happen while switching from ATI to Intel.

Reproducible: Always

Steps to Reproduce:
1. Switch from Intel to ATI graphics
2. Scroll
Actual Results:  
You see repeating patterns and a stuck GUI


The driver of the ATI card cannot be updated because it's a special version.
Disabling the hardware acceleration in FF is a workaround for you
