The ship starts to expel black squares from the engines, is rare because is not a general map render issue, all other items are fine is only the engines from this ship and others in the game (but not all the other ships, the black square are only expeled from some ships).
It only happens when I’m using the Iron Harpy, happens every time. The time was 21:21 (GMT -5), 28th april.
Bug still exists. I have lastest Linux kernel, Proton, mesa. Appears after using Warp Vortex on Tai-Kin and doesn’t disappear. Makes using craft virtually impossible unless you never use Warp Vortex. Perhaps allowing players to turn off whatever graphical thing is causing this would be a possible solution. I have tried altering all in-game graphical settings.
I installed wine-staging (testing version of wine) and no black squares. I’ve not tried with regular wine, that may also work. This should not be considered to be an ideal solution as my fps has taken a hit.
For those with clearance level 15 or above: if you’re moving from Steam to wine, you’ll have to copy over the ship presets file (replace [custard] with whatever system username you use):
