Hi All, I have an application,that renders to Texture using PBO like said here (http://www.songho.ca/opengl/gl_pbo.html) and some other drawings that are handled with VBO's.

When I run my application with '-Djogl.debug.DebugGL' argument, I had the following messages:

GLDebugEvent[ id 0x20071
	type Warning: generic
	severity Unknown (0x826b)
	source GL API
	msg Buffer detailed info: Buffer object 1 (bound to GL_VERTEX_ARRAY_BUFFER_BINDING_ARB, and GL_ARRAY_BUFFER_ARB, usage hint is GL_STATIC_DRAW) will use VIDEO memory as the source for buffer object operations.

I have NVIDIA Quadro FX 570 with the latest driver version. (With old driver version it doesn't print anything like above).

By the way, my app runs well.

Do you guys think that I'm doing something wrong? Have you ever got any of this messages ?
