Caused by rBc30d6571bb47: Add support for tiled images and the UDIM naming scheme

@Lukas Stockner (lukasstockner97) : mind having a look?

It's the same behaviour I saw with the patch earlier, so may be the same problem that existed for the cycles preview window.
I can confirm this problem too since we use Box mapping extensively and we saw our scene going pink suddenly
