Spoiler warning for the location and related things. (Relatively big spoilers)
Non-modal UI
As visible in the video and screenshot, the names of some items in my inventory appear briefly next to some of my attached items, despite the fact that i did nothing that should trigger that.
The names are specifically those of the last items i'd swapped into my inventory, and they are next to the very parts i swapped them with!
I don't know much about auto-repair or whatever that feature is called, but it's probably related?
One last potentially relevant thing : When i flew past the Fortress, the only thing that got hit was my Sigix Broadsword, which was inactive then. I did lose propulsion integrity from burnout both before and after, though.
I don't have a video editing software, so the method i used to make the video of specifically those seven seconds was to re-record part of the longer video i had. (This is why some pixels appear at the bottom-right corner of the screen on the last frame.)
