LWJGL Renderer

[eMKa]

I get

org.lwjgl.opengl.OpenGLException: Invalid operation (1282)

I’ve seen this error commonly happens when using more than one thread but I do have one thread only ! Here’s the complete stack trace :

org.lwjgl.opengl.OpenGLException: Invalid operation (1282)
at org.lwjgl.opengl.Util.checkGLError(Util.java:56)
at org.lwjgl.opengl.Display.swapBuffers(Display.java:566)
at org.lwjgl.opengl.Display.update(Display.java:582)
at com.xith3d.render.lwjgl.CanvasPeerImpl.renderDone(CanvasPeerImpl.java:772)
at com.xith3d.render.lwjgl.CanvasPeerImpl.display(CanvasPeerImpl.java:958)

at com.xith3d.scenegraph.View.renderOnce(View.java:616)
at com.xith3d.scenegraph.View.renderOnce(View.java:549)

It seems like it happens just before swapBuffers() (swapBuffer calls Util.GLCheckError() before really swapping buffers).

See : http://www.java-gaming.org/forums/index.php?topic=14118.0

Anyone has an idea to fix it ?

Any infos welcome, I’m not a LWJGL guru but I’d like to see if I can increase performances using LWJGL.

either inject lots of Util.checkGLError or use GLIntercept to locate the offending opengl call.
