@dpamio I don’t see any Sass file in the project but styl files for styling. The could you posted could possibly be fore quasar 0.17.
I got this to work by inspecting the element and playing with the css:
First, add a background-color and opacity as 1 to q-focus-helper. Then remove the opacity and background-color from the q-focus-helper ‘before’ and ‘after’ css.
Now you will have an opaque background colour when hovered but it will cover the text.
So add z-index 1 to q-item__label.
This is a pretty crapy solution!
