Huge performance issue on some devices with PowerVR GPU

There is a huge performance issue in AIR, starting from version 22, which happens only on some devices, for example Amazon Fire HD and Asus Zenfone 2. I found that these devices have the same GPU - PowerVR G6***. This issue impacts the performance so much that even simple scene with couple of images renders at 15 FPS, instead of 60.

This is the only issue that prevents us from using new AIR version, so we stick to v21, which is the last version that works correctly. We have 170M downloads on mobile, updating to v24 would have a positive impact to our users.
