Hello, I've been developing an application for 4 years and it always worked like a charm in AMD/ATI graphics cards / igps, but now after installing Catalyst 13.04 the only I can see is a blank screen.
The last Catalyst I've been working successfuly with are the 12.08 with a HD6670 graphics card. Below I'm posting the C# code to initialize the OpenGL context.
Please, could anybody take a look at this and help me to know what could make the code incompatible with the latest Catalyst drivers?
