Hi there! Here’s my problem… I publish an android game with this new libPNG with API 19 and I’ve notice that some textures are not showing during game. Sometimes the texture is loaded, sometimes not. If I use the API 21 all the textures become visible. I’ve already try to increase the memory poolsize and a bunch of other things. Is there a minimum API to use this lib? It’s a bug? I’m stuck here trying to solve this issue. If you have something to help me, I will be thankful. 
By the way, worked for me with 4.13 and 4.11 to.
