Thank you for your feedback and comment! Will look into this, as performance is key!
If it helps any, the VRAM leak and black screen for the star chart appear to be different issues. The VRAM leak happens when I click the Fractured Void button. The game as a whole starts lagging when I click it and VRAM usage starts raising. The interesting part about the VRAM leak is that for some reason, most of the leak ends up in shared VRAM instead of dedicated VRAM. Also may help to mention what browser I'm using as well. It's a Firefox fork called LibreWolf (version 139.0.1-1 specifically). The issue would likely appear on base Firefox as well, though. The primary difference between Firefox and LibreWolf is that LibreWolf is focused more on privacy an security.
