You can't manually clear image memory. C2 uses only what it needs for specific layout. When new layout is loaded then all not needed objects are released from the memory and new objects for next layouts are loaded.
Image memory in the debugger will only show if you use WebGL
Thanks for the info! Very helpful!
i don't think the lack of memory the source of your issue, all recent phones have 2GB of RAM, which is used as graphic memory too.
What do you use to export your game? cocoonjs, intelXDK...? can you export a capx (i'll understand if you don't want to)?
I also thought that the problem is not in this, but I checked everything several times. I do not know then what could be the problem.
This is what happens:
It should be like this:
I use TiledBackground
I exported through the cocoonjs canvas+
Unfortunately I can not give capx
