preserveDrawingBuffer on ipad ?

Hi Klaus,
I'm building a snapshot plugin for krpano with WebGl and preserveDrawingBuffer and it works great !
I only have one issue on my iPad 2, if I take the screenshot before all the tiles are loaded then it works as expected, but if I take the snapshot when all the tiles are loaded then I only have a blackscreen instead, like if the drawing buffer was empty ?
Tested on iphone it works great too, no issue on android, for now only my iPad 2 have this problem...
Do you have a clue ?

here is the demo : https://www.360images.fr/krpano_snapshot/

thanx !!!

Maybe it's the iPad 2 itself - too few resources...
Have you tested other iPads as well?

It looks it works on Ipad2 Air...
I've tried with increasing memory.maxmem with no success...
So the ipad2 would clear the drawing buffer when the tiles are loaded to free memory ?

That's a krpano settings and not related to the iPad 2 internal memory usage!

???
I don't know that the iPad 2 is internally doing in this case.
Maybe try reporting the problem to Apple, but I don't except any fix for an old iPad 2 from them...
