fix nextRgba not called when switching to texture render (#8792)

Browse Source 
Because rgba buffer render doesn't support multi display, when switch to
multi display, it is possible that rgba.valid has been set to valid but
nextRgab is not called, when switching back to single display,
rgba.valid is still true.

Fix by rgba buffer, rgba texture and  gpu texture using different messages.
