Some years ago I made a maple frame and panel door for a fish tank that was too small perfect joinery but wrong size.
I left it out in the weather to see what it would do.. The maple panel pushed all the joints apart but what was surprising was the shape it took. Two opposite corners grew in length even though it was flat sawn. It looked Diamond shaped.
When I make a cabinet I’m carful where I use flat sawn parts and consider rift sawn the best for stability.
Good Luck
