Blank frame in animation appears as black frame in current app store release

GamePizza

using GS 10.3, have an actor that is 225x225 but is using a clear frame, basically has no image.

test on iPad 2, and on GS screen, blank actor does not show up as anything. It is blank as expected.

But when game is released and downloaded from app store, blank actor appears as black 225x225, not clear, without image.

have an Animate behavior in the actor. When it runs, the images in the animation appear correctly, except where there are "blank" frames in the animation. These suddenly appear as black frames as the animation runs. Released same app before, 11 months ago using GS 9.90 and didn't have problem.

Will try replacing the blank frames with an image of 1x1 pixel.

This is a reported bug. When you publish an app that has blank images they show up as black images on non retina devices. The game looks fine on the GS viewer and retina devices.

Do you have resolution independence check?

Wow - as far as bugs go this is a big one!
Hope GS get this one nailed soon!

I am getting this also but it is not an entirely blank frame. It has a small graphic element. I did not know this bug existed or the details. Thanks.

I was/still am experiencing this issue, and it has been reported. From my test I think somehow GS detects blank images as 0kb files so it displays black. Seems to happen during publishing.

For now I have an image with 1 pixel of 1% opacity and it seems to be doing fine as a band-aid fix.

thanks will try that @natzuur

I will be looking into this bug on monday.

I also saw this bug on the game Rocket Rabbit and he said it was related to 8bit PNG files according to the dev. 24 bit .png versions fixed it perhaps. Alternatively to bypass the bug have a single pixel with a lightly opaque colour to make it work on a larger blank image. Back in the 90's we called this a null pixel (null.gif later called 'spacer') - but in this case you bury it in your blank transparent image. Likewise in background images that are full frame stacked with pixels to the brim - and GS compresses them to lower bit values - just pop a slightly alpha pixel in there to bump them up to a reasonable and consistent quality. This is a way to graphically hack dumb converters to doing what you want.

Oh, and as a side note, you can not have a plain black and white iOS logo - that is an issue a friend recently came across. So putting non-visible colour noise on the image fixed that apps problems in the iOS Apple App Store.
