The application works as follows: In the main thread we create an OpenGL context. We then start a background thread with its own X11 connections and then create an OpenGL context in this thread with sharing of textures turned on. The main thread and the background thread will not be terminated until the application is terminated. Neither thread will use the others X11 connection nor its OpenGL context. The background threads draws into an offscreen texture. This texture is passed to the foreground thread which will then display the texture on the screen using two triangles. The idea is to ensure that the GUI is always responsive regardless of the complexity of the rendering.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
