This has been happening in my base since the update. I thought it must have been my computer until I was on voice and others said they are seeing something similar. It happens inconsistently, or I am not certain what triggers it.
It happens at the same spot in my base and it has happened out in the wild too.
Here is the short video showing it:
Here is a screen grab of what is flashing on my screen:
I can confirm this started (for me, anyways) with the update just before last Halloween. The Oorty Update. Part of me thought it could be intentional because it was reminiscent of running thru leafy branches like in a horror film. Time proved that was not the case. I just refer to it these days as Oorty’s Curse.
It does seem to reoccur regularly in certain areas in my home beacon, but I’ve never collected the data. I’ll try to pin a location or two down. It’s not just any colour foliage that flashes; sometimes mould will flash onscreen as well.
