Lag on realm quest on overworld

Playing on windows. Version 1.0.3. When I enter a realm it lags. When I complete the realm quest it stop laging. Lag in overworld, not in battle. The lag isn’t big, the game is still playable. Liking the game so far, at depth 30s. Sorry for my english

Solve the problem. I had the game in full screen that cause the lag.
Edit: false alarm didn’t solve it. Sorry for bump.

I had this issue and a post saying extra save datas was causing it. I deleted 3 I didn’t need and it stopped lagging for me. It was exactly what you said, it lagged until I completed the floor quest.

This is my only save. Cloud save maybe?
