Same guy here who started the github thread 🙂
Just want to add that actually the first Courusant level actually also has these bugs just to a lesser extent because of the environment type.
When you enter the dark areas where its basically showing you how to use your lightsaber for light, it is way darker than it should be with RT on, and you can find some areas where if you have shadows above low and RT off it will exhibit the same flickering squares issue that you see on the other plants.
Also, having finished the game on other hardware and re-tested on Arc, the shadows issue happens on pretty much every plant of the game, just some are more apparent than others.
Hopefully EA and Intel can work together to sort this, as it seems to be an Arc driver but rather than a game bug given that its fine on other cards, unless they worked around a game issue.
