I have no idea which component I should assign this report to, I hope it moves it to the most suitable location.

When selecting an update listed in Discover, using the Dark Breeze theme, the checkbox has a low contrast.

Low contrast in the two situations below:

This is a visual incompatibility between the Breeze-styled checkbox, and the list items in Discover. We have a few options for how to fix it:
1. Change Breeze to improve background.border contrast when a checkbox is drawn on top of a selected list item using the current style
2. Change Discover to use a custom selection style for these list items that incorporates a lighter background color 
3. Change Kirigami to use a custom selection style for all list items that incorporates a lighter background color (which is something we've wanted to do anyway) and then port Discover to use it

Given that we can't implement #2 or #3 for QtWidgets apps, #1 is our best bet. Moving to Breeze.

In the future please attach images, rather than pasting a link. The link can die.
