Hmm, the assertion was put in to avoid copying with the same texture as src and dst. But the fact that src.id and dst.id are zero is particularly odd. I don't think that should be possible, so something has gone wrong.

I just experienced it on https://www.leroymerlin.fr/v3/p/produits/radio-de-chantier-my-tube-grey-perfect-pro-e1400026730 but cannot reproduce :/
