I know there are similar questions to this already however I've followed them and I'm still experiencing some trouble. I'm trying to theme the show app grid icon in the dock with this icon https://github.com/gusbemacbe/suru-plus/blob/master/Suru++/apps/64/ubuntudash.svg
However, when I replace the
view-app-grid-symbolic.svg file with it I either get a blank white icon or no icon at all. Any help would be appreciated.
I'm using the suru++ icon theme and it would be awesome to have all the icons in the dock uniform including the show apps launcher.
