Yeah, I'm very aware of the 2880 pixel limit on the BitmapData class (didn't I mention that?). Here's the specific scenario: I have a sprite that's parented to the stage. I fill the sprite's graphics with a bitmap fill sized around 10000x10000. I'm "scrolling" around by shifting the sprite's x/y. Everything works exactly as expected until I set the x/y to a value greater than 8192 (or less than -8192) at which point the sprite stops rendering. So, yeah, I'm sure this relates to an internal limits of Flash, but the magic numbers I've seen are 2880 (for the size of a single bitmap) and 10,000 (for the size of text fields and the max size of a "canvas" in Flash 8). 8192 is a different magic number (apparently)... I'm just trying to confirm that that is the limit for x/y before I start "virtualizing" things to work around it. Note: it's not the same as the 2880 bitmap limit because everything renders correctly until I *move* my sprite to that x/y... it's still the same size and still occupies the same size on the screen.

I'm surprised it didn't fail sooner. 2880 is the limit for most things. After that it is unpredictable. That's why DataGrid and other list classes virtualize their children.

I find that if I position a DisplayObject (specifically, a sprite) beyond +/- 8192 it vanishes from the stage (well, it stops rendering)... I couldn't find any docs that attest to this limit... and it doesn't seem to matter if I turn on cacheAsBitmap, etc. (besides, the bitmap limit is 2880). Is this a hard limit, or can it be worked around with a proper use of cacheAsBitmap and scroll rects? Or am I basically going to have to manage the display list manually? (I'm panning across a big sprite that has children sporadically placed across it, each one within the bitmap limits.) Thanks, Troy.
