Trouble rendering a simple OpenGL ES 2.0 application

[xxoxooxoxx]

I have made a simple OpenGL ES 2.0 application which uses SDL2 to draw a coloured triangle. However the output in raspberry pi is different from my linux dekstop. Below is the output from my linux desktop:

Here's what raspberry is rendering:

Note that both share the same source code.
I am using Raspberry Pi 2 Model B.

I doubt you'll get useful feedback if you don't post at least some of your code.
