Citra freeze when changing game speed limit during emulation

Issue:
If I change the game limit speed during the game session it works fine, but the bar under screen keep saying it’s running at 30 fps. After some seconds, it freeze for an considerable amount of time and then, when unfreeze, the bar underscreen refreshes showing the right value.
In the first seconds before the freeze, Citra runs fine at the speed that I’ve set.

UP: I’ve noticed that it happens more often if, after have changed the speed limit, you do nothing and wait.

I also have this issue, but with every single Graphics menu change (example: if I change resolution from 5x to native, everything gets frozen and unfreezes after a minute).
