Endless, can you maybe email me a side loadable example of double-buffered tearing, so I can file a bug on that?

Re: getting a black image on roScreen

Yep. Yep. Yep.

Thanks fellas!

Two more things
You might move your swapbuffers outside the if/then so:


That works, but if I put my clear to the beginning of my while statement and before my if/thens, it causes a flicker. froze my box once. I move it to the begining of my if/then where things are drawn, it works fine, no flicker.


Also, when I draw a 720*480 image it's fine, but if I use a 1280*720 image, it goes black, and eventually freezes my box (while playing video). I assume that's a memory issue. Is there a way to look at how much memory is being used and what's available? That would help me out in determining what image sizes I can use and when I'm running out of memory.

We are all wondering that ourselves. Getting that was not easy.

Re: getting a black image on roScreen

Dang, that sucks. It seems like if there's more things like that that'll keep us from spending time chasing our tails, and spending time on getting things done, it'd be a win win. Oh well!

You can "genkey" and you can "press"
