acceleratedrendering = true and ink = NOOP don't cooperate :-/

Hi Klaus and All,

I'm just now trying to get my head around accelerated rendering.

I don't have access to Windows, so can't comment specifically on what Klaus discovered.

However, I can confirm a problem with INK and accelerated rendering on LC5.5.1 when running the app on iOS simulator or device.

I noticed this when updating an app where images are dragged around…that's why I was using accelerated render….

I've set the INK on the draggable images to "clear" when the image is first shown to the user… with accelerated rendering set to false, the image is black…. with accelerated rendering set to true, the image seems to be stuck in its original color...

In other words, if I change the INK state to clear while accelerated rendering is true, nothing happens… but, the image changes when I set accelerated rendering to false… 

I can tell by using the Inspector that the INK of the image has been set to clear….

It's easy to duplicate this problem, but I'd be happy to send out a small stack.

Interestingly, in my main project… setting INK to clear still works on my Mac… but, the small demo stack doesn't work.

Anyone have a work-around for this INK bump?

be well,
