android - cacheAsBitmap causing graphical glitch on GPU rendering mode in Adobe Air, when app runs on Dell Venue 8 7840 -


(if you'd like, download .zip of source code demonstrates error.)

start off new adobe air android app, set gpu rendering mode. add displayobject stage, , set .cacheasbitmap value true. run app on dell venue 8 7840. here's screenshot: green square simple movieclip shape drawn using . .graphics property. glitched out space supposed red square, drawn using same method, .cacheasbitmap = true

enter image description here

this happens on particular device, using particular rendering mode - updating android os version 4.4 5.0 doesn't fix it.

any ideas on what's causing this, , how fix without using different rendering mode or not caching graphics bitmaps?

i had these unexpected results before, twisted them adding cacheasbitmap cacheasbitmapmatrix scaled 2x matrix. takes more memory did trick few times.
