Hi,

I installed gnome3 from testing today, and it works fine so far. But in dual screen mode, the gnome-shell uses between 50 and 100% cpu continuous. Just after login, without any other programs running.

If I switch off one of my displays - it does not matter which one, the laptop display or the vga plugged - gnome-shell runs on 1% cpu usage again. It is also possible to switch between the displays without problems, as long as one of them is switched off.

Since this is a 6(?) year old Intel 915GM chipset, it's maybe just related to too little grafical power.

Is anyone able to confirm this on a more powerful machine?

The issue is probably that the dual screen desktop size exceeds your card's maximum texture size, triggering software rendering fallbacks in OpenGL all over the place.

Thanks, Jan. I also think so. -- chris
