The last update uniform focus style has a new mixin which is add an outline the input fields, selections and other… This is a great for accessibility but we use a border-radius: 4px on input fields. Is that possible to override mixins or add a border-radius: 0 into the core mixins.scss and this generate border-radius: 4px to 0 on focus?
On the left it looks like now and right is after border-radius: 0;
We have an internal theme that has rounded corners for buttons, and I don’t see a similar issue as yours. Can you provide maybe a bit more context, i.e. a larger screenshot so I can see which button this is? Let me know if you are using a public theme, I’m sure this is fixable.
