Which video driver are you using? Flash is binary blob, there's probably not much we can do about it.

if youre using an intel driver it *might* work by setting MigrationHeuristic to "Greedy" in xorg.conf

On further investigation, I think you're right, it might be an X or driver problem. Do you know if pixman in arch is compiled with MMX support? reports on the net of flash problems were tied to that package:

--------------------------
after looking at the many reports on this and doing some investigating, it was indeed a pixman problem. The new pixman enables sse2 optimizations (which aren't good for older boxes ), and in patching it out, the MMX stuff was removed too.

xf86-video-ati radeon driver, btw

Setting migrationHeuristic in xorg-server 1.5 will break a lot of visual things on your desktop, so it's not advised to enable this.

really? i have had it sat for a month or so now and haven't experienced ANY issues. So i don't think the picture is quite that simple. I use nvidia binary-blob.

I've found this can sometimes be fixed by restarting firefox, especially if it has been running for a while. However, flash has been choppier than normal lately and crashed my browser a few times the last couple days.

Downgrading to flashplugin9 in AUR seems to have solved this for me...
