Citra suddenly slow even though nothing has changed

Issue:
I installed Citra yesterday and started playing FE Echoes. everything was running perfectly smoothly minus cutscenes which were, understandably for my laptop, running a bit slow.

I played a few hours yesterday and a few hours today, stopped to have dinner and closed Citra. But when I came back opened it and turned the game on suddenly everything was going drastically slower than before. the overworld map was as normal but the title screen and battle map were going much much slower. Nothing changed between sessions but it was suddenly just. slower.
