Ugly OS upgrade banner text with backdrop styling
When the window doesn't have focus, the text in the upgrade banner looks like this:
@jimmac I've seen this problem before in other places, basically anything with "art directed" custom CSS needs to either account for backdrop or disable it. In cases like this one where the CSS is basically part of the "content" it probably would make sense to just disable it.
Some ideas:
- make it easier to test backdrop styling (ties in with gnome-builder#935 (closed))
- a style class to opt out of backdrop styling for specific elements
