Comment 105 for bug 217580

Sorry Alex,
     I didn't checked the linked bugs actually!

I'm very glad that eventually we all have been able to track this down!

I'm not sure this might be a driver issue, IMHO. So far there have been
reports of users with Nvidia, Intel and ATI cards (fglrx, see first post of
Mozilla bug 422330). A friend of mine keep telling me about this slowness on
ATI + radeonhd, also.

I think that users that own older PCs tends to notice this much more - my
CPU is a 1.6 GHZ AMD Athlon, and scrolling is VERY slugghish. At work I use
a much more recent notebook with ATI + radeon, and the scrolling slowness is
still there, but a bit less relevant.

So, we've likely found the long standing bug that is affecting us, good. On
bugzilla I see the status is NEW, and no more activity since August 2008.

Alex, is there something we can do to speedup this bug fixing? Perhaps
aatdark work can be useful, since it provides a clean testcase? Will FF 3.5
still have this bug?

Thanks
