Synthesis screen is black after returning from battle.

After entering a map and battling a creature, and head back to Atelier to use the cauldron, the alchemy screen is black. You can still move the cursor and select things, but you can't see what you're actually selecting.

This is an issue caused by running in fullscreen mode. Unfortunately the only way around it that I know of is to run in windowed mode instead.

I have no idea if this will ever get fixed; Koei-Tecmo's history with Atelier ports has been mixed at best, unfortunately.
