Java2D OpenGL Remarks
* * To avoid any conflicts with a potential Java2D OpenGL context,
* you shall consider setting the following JVM properties:
* * This is especially true in case you want to utilize a GLProfile other than * {@link GLProfile#GL2}, eg. using {@link GLProfile#getMaxFixedFunc()}.
* On the other hand, if you like to experiment with GLJPanel's utilization * of Java2D's OpenGL pipeline, you have to set them to * * *
Disable Background Erase
* * GLCanvas tries to disable background erase for the AWT Canvas * before native peer creation (X11) and after it (Windows),
* utilizing the optional {@link java.awt.Toolkit} method disableBeackgroundErase(java.awt.Canvas).
* However if this does not give you the desired results, you may want to disable AWT background erase in general: * * *
