That's because of accumulation buffer, yes. I've made simple SDL test
(http://amdmi3.ru/glaccum-test.tar.gz if you're interested) that repeats
the bug:

./without_accum
Seconds: 20.00, frames: 10335, FPS: 516.739
./with_accum
Seconds: 20.26, frames: 10, FPS: 0.494

Well, it's really simple to turn of glAccum stuff in gnash code, so I'll
patch it for FreeBSD port, as a workaround for now. Still will do some
digging on why's accumulation buffer is so slow here.
