Slow Scrolling in Firefox with Compiz Fusion[solved]

[rahulthewall]

As the topic says, scrolling in Firefox (using 3, it was the same with 2) is so horribly slow, that I can not simply use compiz fusion. Anyone has an idea why this might be happening?

That happens if you use fglrx. You shuld update to the latest drivers, the issue has been improved a lot. Also try

I have an Intel 945 GMA, so I do not use fglrx. However, I will try this option and see what happens, if it makes a difference on Intel Cards.

Note: I have an old radeon so it might not apply for intel but here what I found with my graphic card.

I found that with my radeon the EXA scroll much better than XAA mode Also compiz 7.6 from the desktop-effects overlay work much much faster than the portage 6.0

It seem from the following wiki that intel card can set

Option "AccelMethod" "XAA" # XAA & EXA are valid values

EDIT:hmm it a wiki page candidate for deletion and I can't seem to get the link correctly. I haven't read the whole thing it just the last xorg.conf example too see that EXA or XAA is indeed an option not sure if it realy work

EDIT2: here an other xorg.conf example which use XAA http://gentoo-wiki.com/HARDWARE_Dell_Inspiron_E1405/xorg.conf

However a quick google search tell me that lot people have problem with intel graphic and EXA and compiz so It might not work for you.

Give EXA a shot if it crash the whole thing revert back to XAA or switch to XAA if it's already on EXA

Good luck
