We dont know is this bug similar or not, cos I have even greater tearing and jumps on single core computer (just tested). And – let Adobe check this issue and let Adobe will decide – is it double-buffering problem or smthing other. Your issue example is more fundamental, so it would be great to have this bug in database. I try to popularize it and bring as many votes as I can.

I’m sure Adobe would be quite aware of it, there are a few existing tearing bug posts on there – mostly focused on tearing video. One on multicores- saying that it doesnt happen as much with a singlecore (fix = use older player which only supports a single core – interesting)
http://bugs.adobe.com/jira/browse/FP-2054
i have voted – but by the assignee’s status of priority=none – i dont think Adobe will give it much attention. They seem to be adding better hardware support etc. lately, so lets hope they work on double buffering in the future.

If you submit this issue into Adobe JIRA – give us a link here – we will vote for it.

We have Q6600 quad core, ATI4800 –
so you are saying that things still tear – that is what i am saying too. It should be a bit better in wmode=direct – but still jumps (not tears) every now and then.

I’m sorry, I’ve experiment with you code and… your case isnt my case. I suppose this is internal rendering issue of flash player, because I’ve test your code with copyPixels to background bitmapData and even bitmapData.scroll method, which should give us a guaranty of synchronous circles moving. But I’ve seen tearing anyway.

Are you testing this on dual CPU computer? Mine is dual, I will try it on single CPU comp.

So yes – you can see tearing in scarygirl – for instance, if you go to the swimming level (second one) and swim up/down you can see noticable tearing. It isnt as much of a problem there however, as the motion is quite slow.
