Pretty often(intel macbook, currently running sonoma but this has been happening for years), my Fusion browser "shows through" other applications. If I click or ⌘+Tab back to Fusion and then return to the other application it fixes it ... for a while! I'm not sure what exactly causes it to re-occur.
I often am working in several tools at once, so this is pretty annoying.
I can reproduce this 100% of the time by starting Fusion, and then while it loads switching over to any other application (Firefox, Mail.app, Slack, Affinity Designer, whatever).
I normally work with an external monitor but this happens even if it is not connected so I do not believe that is related.
