Camera.targetTexture confuses camera callbacks
Camera.targetTexture or RenderTexture.active with Camera.RenderWithShader are making trouble.
If I set the camera's targetTexture in OnPreRender or OnPostRender in a script attached to the camera, it turns out those functions get called only once. Not once per frame, just once. The render texture gets filled properly, but the framebuffer isn't filled anymore, as I end up with some empty dark grey scene.
If I put a debug line in Update, I can see it gets called every frame.
If however I set my render texture into RenderTexture.active, then OnPreRender or OnPostRender are called every frame. However my render texture isn't filled (just black and 0 alpha) while the framebuffer is with what should be in the render texture, and my normal scene isn't drawn (or rather is drawn over).
