Rendermode=gpu ignored? in Android 5.0

[Enigmato]

Problem Description:

On some android devices, application falls back to cpu render mode instead of GPU mode,

despite declared in -app.xml (<renderMode>gpu</renderMode>).

Profiled with Scout CC and confirmed x5~x20 increased time consumed in rendering,

indicating AIR runtime is rendering the application's DisplayList  only with software mode.

Steps to Reproduce:

https://play.google.com/store/apps/details?id=com.ggee.vividruntime.game_ticket_1715&hl=ja

Application packaged with AIR SDK 17.0.0.124,

Severe fps drop observed on following devices :

1. HTC Butterfly J HTV31 (Android OS v5.0.2)

2. Nexus 6 (Android OS v5.1.1)

3. Docomo F-04G (Android OS v5.0.2)

Actual Result:

Severe framerate drops to <15 on main menu screen.

Expected Result:

Should be able to achieve targeted 30 frames / seconds with devices listed.

Any Workarounds:

Does not happen in APK files built with AIR 16 build 292.

Does not happen in android devices with OS versions under v5.0

Hi Enigmato,

I am not able to download your app, because of the issue "This app is incompatible with your device country".

But I reproduced this issue in a sample project with AIR SDK 17.0.0.124.  This issue has been fixed in AIR SDK 18. Please download the latest SDK from this link. Download Adobe AIR SDK  and check your project with AIR SDK 18.0.0.143

L‌et me know if you still face the issue.
