Using C “port” of LUA playdate.ui.crankIndicator from:

int clockwise = 1;

int crankIndicatorY = 210;
int textOffset = 76;

totally trashes device performance when drawn on screen:

green section: crank undocked
red section: crank docker (e.g. drawCrankIndicator called)

oh interesting, I don’t know what I’ve done to make that happen

Is the scale 1 or higher?

oh! I wanted to delete the post but clearly didn’t

I tried a standalone repro and couldn’t get the same effect - there is something in my main game clashing with your code, I’ll try to dig further.
