Ionic app mis-registering touches

I’ve got an ionic app has recently starting showing a really odd bug - touches are mis-registering on ios.

On a dialog box with three options if i try to click the first option, the second one clicks, and if i try to select the second one the third one selects. Clicking the third one does nothing (presumably because it’s trying to select something underneath that isn’t there).

It’s happening on a few pages, but not all of them, and i haven’t changed any code, just updated ionic. It’s driving me mad, has anyone else had this?
