• Description: Create a stack of 3 windows.

Make the first window in the stack a tabbed container and add another window into it.

Move up and down the stack, SwayFX will crash when you return back to the top window in the stack (the tabbed one).

I can recreate. Thanks for reporting, I'll take a look.

Thanks a lot.
