Beta 19: Scroll more than 32000 pixels = glitch
If you scroll more than about 32000 (2^15) pixels, objects get randomly destroyed and there appear to be memory leak problems (some objects aren't deleted). I have virtual height set to -1.
An example mfa is here, with some simple object creation:

(The forum still only allows up to 1MB uploads)
If you run this on a PC, it runs as expected. Nothing unusual happens. However, if you run this on a device (iPhone 4), then shortly after the application starts, all of the pink boxes will disappear and the green actives being created will also disappear.
I think this issue is separate to the graphical glitching mentioned here:

For me it got a bit odd behaviour even on PC. Green ones doesn't bounce from the top edge (which is OK cause of virtual height) but it seems that there is quite visible lag in their movement and visibility. Like motion blur.

They're moving up by a random amount of pixels, and since they're also moving quite fast it might be your monitor.
Has this bug been acknowledged?

Sorry, but I do not think this can be corrected. I suggest you test for the position of the scrolling, and at a point reset everyone to a lower position. This is the only way to do it I think.

That's a bit annoying, but I think I might be able to do a workaround like you said. I'll give it a go.
