hi,Rogelio.
Thank you for your help.You modified app it work fine.
But, sometimes applications need to repeated set bufferdata , the same problem will appear.
For example, rendering process is as follows:
1. painting triangle
2. Painting textures
3. Painting rectangular
4. Painting circle
The same problem still happen，it will missing some picture

Best regards!
