[1.1.33] Sprites have disappeared for some entities

[FactoryBuilder]

I don't know everything that has happened. I don't see any pattern to which entities have lost their sprites. I don't know if the sprites simply aren't showing up or if they are off position from their entities. I don't know every entity that lost their sprite.

What I do know is that I switched windows from Factorio to Chrome because I was waiting for my factory to produce stuff so I can do stuff (I don't remember what and I don't think it's important). I switched back and entities were missing their sprites. I do this all the time but for some reason, this time some sprites decided not to show up any more. The sprites I do know went missing are: Tops of trains and wagons (wheels show up), the player, enemies, pumps, roboports, radars, beacons, rocket silos. There could be more that I just didn't check.

I restarted the game and all the sprites are back. This is the first time it has happened and I might not see it ever again. I couldn't find any other reports on this so maybe it's some very very far out edge case that I just so happened to do? Some very specific combination of keypresses and window changing that removed the sprites?
