@piyushsinghania I didn't know the checkbox broke on linux. Here are a few screenshots of how it appears on my system:

Can you make it look this way without the UX breaking? Primarily:

• Maintain width and styling with other elements, the report checkbox should have BG and match the width, as of now even I'm not a fan of the background appearance but will change them all together when doing a UI fix later on.
• Don't use the accent color for the checkbox, it makes the checkbox standout among other elements even when no special importance is given to it. As of now don't change the coloring.

LGTM, failing build is unrelated, hence merging.
