Calling the PD menu from within a Pulp game causes:
The top-left 1/4 thumbnail look broken: unreadable text, unrecognizable icons, tiles generally affected.
If you let the PD sleep with the menu open, when you unlock it again, the tiles are all messed up in 1:1 view.
Version 3.0.3 (which came out yesterday) has something in its changelog that looks like it may be related to this issue so you may just need to update your Playdate to fix this now.
It did fix it! Thanks for stopping by.
