apple Prores is jitter on osx10.6.8 but 10.7 or 10.5 is not

I found a weird issue with Apple Proress and different Osx version

I was having a terrible headeach working with this codec for motion graphics and text on finalcut all the borders of the colors or lines was showing jitter or kind of aliasing problem. so bad that I use proress only for offline and doing all the onlines with uncompress. and I couldn't understand how people use this for broadcast quality.

but I found today something really weird, the same quicktime that look horrible jittering on 3 different computers with osx10.6.8 (2 of them with blackmagic design cards for final cut) when you playback on a 10.7 system or 10.5 system it looks perfect

I just don't understand what's going on? any help? anyone experience the same thing?

this issue is the same on 422, 422HQ or 4444. the problem is on all format of apple proress

I see some aliasing on the text and it is worse on the red text. Not sure if it's any worse than what I expect. But I'm not seeing any jitter.

Is your sequence interlaced or progressive?

is a progressive sequence. jitter is probably not the word is more an aliasing problem.

english is not my first language I'm sorry if didn't explain myself well, is not a flickering thing is jagged borders

I just don't understand why it looks so bad the idea of Apple Prores 4444 is to be use for online high quality purpose. but you can't use that codec for broadcast quality while working on 10.6.8 the only way to do it is to transform everything into uncompressed codec. or maybe I missing something but I couldn't figure it out
