Logic pro 8 problems with mavericks

Question

Logic Pro 8 worked fine with snow leopard. Just upgraded to mavericks and now when the playhead moves across the screen it wipes the track region clean (leaves empty black space). If you use the slider to move the viewable area from Left to Right the area refreshes and becomes viewable again but this is a major pain and a dissapointment.
Anyone else experience this? Know a fix?
Thanks.

Re your comment and assumption: If you choose to buy a new Mac (and that in itself indicates you are not struggling that much financially)  at no point in my post did I say I had done that or even intended to!
Well, to have to run Mavericks and not being able to downgrade to an older version of OS X indicates you just have bought a recent Mac.... because modern Macs cannot run, say Snow Leopard as that particular OS X doesn't support the modern hardware found in recent Macs..
That is, of course...unless you meant there is a different reason why you can't/won't downgrade? If the latter is the case then that is a choice you are making based on your own priorities.. which was the other point i was trying to make.
Re your: and complaining about it here.. is a waste of everyone's time... surely noone is under any obligation to reply, or even to read a post. And "everyone" in this case appears to be just octopi and you! Goodness me.
Actually.. I was refering to yourself (and others who do much the same thing) more than anyone else.... As I said, because Apple 'isn't here" complaining here about Apple's actions is frankly a waste of your time (and efforts) and everyone else's for that matter. hence why I included that link which demonstrates a much more effective manner of getting across your displeasure with Apple's polivies.. to Apple themselves!
I don't believe that octopi's post indicated any form of arrogance or bullying.. Just him venting the much felt frustration over posts from people who don't do the proper research prior to upgrading their OS X and then complaining about it later!
Again, these type of posts are  all too common here and in other such forums.. and after a while it does get a bit old you know.... especially when there is post after post on the same subject which few people take the time to read first before posting up their own post... repeating what has been said countless times before.
So please bear that in mind before passing judgement on octopi who actually does a great deal of good for the most part, and spends a good deal of his (unpaid) time.. helping out other users.. in these forums...
Cheers..
