After reinstalling Windows after a repair, I reinstalled OpenLP 3.0.2. Now the icons (Preview, Project, show desktop...) look simplified and quite old-school. Is this because there are yet more updates from Windows that will eventually give me access to those shapes and colors, or is that the new look? The program itself is black and white and - well, old, but everything works properly.
Additionally, I cannot force a theme on any Slide. It always shows on Default theme.
Here is an image of my view.
