Hi David,
Unfortunately, any relevant details have faded from my mind. You may need to follow up with QNX Support to get the
issue sorted.

Subject: Alpha Blending w/ OpenGLES and OpenKODE
Hello everybody,
we have an issue using QNX 6.5's OpenKODE Driver for OpenGLES (both 1.1 and 2.0)
Our test case basically is:
- Create EGL Display and Configuration
- Create OpenKODE Context on top of it
- Paint a green Fullscreen Rectangle and a smaller, semi-translucent blue rectangle
=> The blue (getting dark cyan) rectangle also changes background transparency so you can see the layers behind that
application
Doing the same steps with a Screen Context instead shows exactly what one would expect: A opaque dark cyan rectangle
with green surroundings.
I've attached the test application.
Any idea?
Specific information needed?
