7. This one is actually possible to work around through a side effect of a major technical game development decision by Schema: The choice to use OpenGL and leverage Java's cross-platform portability to allow Macs and Linux to play StarMade as readily as Windows.
OpenGL has issue with multiple transparent/semi-transparent graphics overlaying, which is why if you use a camera in a bridge/cockpit with glass in front of it, you won't see enemy missiles coming at you even though they're right in front of you. This also works with suns (at least with bloom off; don't recall if they hide with bloom on as I turned it off for performance) and all beams. Place a camera block on your salvager, behind a block that comprises your bridge/cockpit window. Switch to it before mining, and no more beams; you'll still get the blue overlays on the mined blocks, but without the beams those should eat less GPU while still letting you see where you're zapping. Another camera block on the ship without glass in front can be your standard navigational view, so you can see suns and enemy fire.
