Cocos2d-x drawing on sprite task

You need to fix the source code so that visual artifacts disappear.

Build on Linux

cmake .
make 
./bin/Cocos2dxDrawingArtifacts

Build on & run on android

Edit proj.android/Makefile

cd proj.android
make 
make run

... or you can do it in a different way but be sure that it will work for me

How the bug may look like

Hint

Artifacts disappear with text removing
