This glBlitFramebuffer() error is caused by using render buffer storage GL_DETPH24_STENCIL8. It works correctly with GL_DEPTH_COMPONENT24. The GL_DEPTH24_STENCIL8 was recently added to work around a different glBlitFramebuffer() bug on Linux / AMD. But we do not request nor use stencil buffer.

This change breaks Greg's glBlitFramebuffer() Linux / AMD driver work-around.

Made AMD fix first OpenGL workaround and made conditional on the Linux/AMD combination. Since the Windows driver shares a lot of code with the proprietary Linux driver, the workaround will probably be needed there as well. Haven't checked yet if the fix is needed with the open-source driver.

Open-source driver only supports OpenGL 3.0, so Chimera2 doesn't run.
