When the Ray Cast plugin is higher in the list of plugins than the GPU Glyphs plugin, enabling ray casting moves the GPU glyphs to the bottom left of the screen, as if the camera is wrong. Turning the visibility of the ray cast plugin off moves the glyphs to the right position, and when the plugin is turned back on, the glyphs stay in the correct place. If the Ray Cast plugin is loaded after the GPU Glyphs plugin, everything goes right. Probably a problem with initialization.
UPDATE: None of the CPU values of the GPU Glyphs mapper seem to be different when the glyphs are in the wrong position, so it's probably a problem in some internal GL value. It's either a value that isn't properly reset when the Ray Cast mapper is done, or a value that isn't properly initialized in the GPU Glyphs mapper. Difficult to debug the shaders, though.
