I doubt that's an intended behaviour: After running a Cart that's using the "FILLP"-Command, every Draw in the Sprite-Editor that includes Pencil or Shape (the last one; not shown in the GIF) also uses this pattern:

On 0.2.1B, it's possible to use "fillp(█)" (or simply reboot) to solve that Problem...

(I was working on a Game and tried to change a Sprite, and I wondered that I suddenly couldn't overwrite some Pixels in the Sprite anymore. I was like "what the Hell is going on there?" until I discovered that^^)

this a feature actually - awkward maybe

Yeah, this is a new feature that was intentionally added. Go look in the changelogs.

Thanks for this, thought it was a bug too. would prefer it to require a poke, such as how poke(0x5f2e,1) makes the palette persist.

@Munro

In fact, I'd say that very poke is probably the one it should be gated by.

I suppose it could have more than one bit for what persists, like 1 for persisting palette, 2 for persisting patterns, etc. So you'd poke 3 to persist both palette and pattern.
