Sorry, I didn’t get the E-Mail notification for the response for some reason. Anyway…
Are the purple parts unresponsive in fullscreen too, or only in borderless? Since the screen aspects are different in all 3 cases it’s an important detail so I could reproduce the issue on my end.
The answer is “yes” for the axe and the eagle, although you can go a bit higher on the eagle icon (just above the torso).
