Timed out waiting for UIComposeThread_0

I`ve recently install 3.1-alpha4-SNAPSHOT ide and upgraded my old project to use new sdk jmonkey. When i attach my TouchListener which extends BaseAppState the console is getting spammed with this message W/hwcomposer( 181): [WKR] Timed out waiting for UIComposeThread_0… and the movement of spatial gets laggy. Can you give me some general implications what might cause this problem or what does it mean.

THIS happens when I run the project on physical android device.

wrong game logic public void update(float tpf) was adding spatial nodes in internal loop :smiley:
