OK, comparing your example app to one of the OpenGL examples included with FPC. I tried to see if the API calls are similar. If I comment the 'doUI' call inside the display() method, then I get a black window, and NO error output to the console. Further investigation insid doUI() method. I commented the whole body, except for the ui._begin ... ui._end. I then uncommented the body one line at a time. As soon as I uncommented ui.doCheckButton(), then the errors to the console window started appearing. I then kept following this "debug method" down to GLUIPainter.drawCheckButton. If I commented the call to drawBoolFrame(), I actually get to see text on the black window! Minor progress. :) This allowed me to re-enable all lines inside doUI(). I now see two lines of text in the window, and a new error message in the console output. "Fragment shader compile failed" No idea if any of this makes sense or if it will help you find the problem. But hopefully it will bring you close to a solution.
