[Stage3D]The ATF compress texture quality loss in some phone.

I'd love to see this fixed.

Issue is still reproducible with AIR SDK 22.0.0.153 released last friday

Issue is still reproducible with AIR SDK 22.0.0.89

Issue is still reproducible with AIR SDK 21.0.0.176 released today

i really wish Adobe members fix the problem.

Still reproducible with AIR SDK 21 Beta

Still reproducible on LG Nexus 5X after rebuilding ATFs with 20.0.0.233, setting app namespace to 20.0 and swf-version to 31

Issue still persists in AIR SDK 20.0.0.225

i find a solution.

don't use "-r -q and  -4".

just use -n 0,0(if you not used mipmap)  and -c e.

png2atf.exe -c e -n 0,0 -i "xxx.png" -o "xxx.atf"

ok. have a problem: the atf file will very big.

but you can use tool compression the ATF. The compression ratio is very high

when you loaded in memory get a ByteArray. use ByteArray.uncompress() method get the raw data.

upload to GPU will rapid.

when you uploaded to GPU, don't forget call ByteArray.clear();
