Still doesn't see it as an issue, just a difference.
The other things seem annoying, but again, I'm hardly seeing these issues. There is some light flickering occasionally, which I can also cause to happen by fiddling with the VR headset (Oculus Rift). The FSS space has been well behaved otherwise.
I wonder if some of the graphics issues people are experiencing are due to outdated drivers, as as been suggested by others. I tend to update as new NVIDIA drivers come out, with the rare roll-back if something breaks. I run ED in VR, using 2 x Geforce GTX 1070 cards in SLI. The game generally runs well on Ultra, with about equal load on either card. I recently saw some frame rate drops near shards PoIs on planet surfaces. But whether that was normal (never saw them before) or an issue with the coinciding April Update, I don't know.
The centre-on-main-body feature of the FSS zooming could be an unintended change. Not sure if it is a regression though. Have FDEV actually said it was?

Couple of thing to disect there.
Firstly, the graphics issues
The graphics issues could be many many things, and I wouldn't begin to assume I could even know the answers, it's a custom engine doing a lot of crazy and complicated things, all I can give is my own personal experience, which is that I updated my graphics card drivers a day after the new patch was released, and that the same graphical issues existed before and after said graphics driver upgrade.
However, my own graphical issues are vastly less problematic than some of the videos I have seen, I merely get all of the graphics being heavily over exposed (very very bright) after zooming back out of planets -sometimes-
And if I then exit the FSS while this is happening, this overexposure exists over the entire game output (UI, Background, ship cockpit, any objects like stations - it's over the entire screen so I would guess it's coming from the system which they use to "tone and colour grade" various parts of space, total guess, though)
I use an AMD card as opposed to Nvidia, and I think I've only seen videos of the entire UI overlay flipping round from people using Nvidia, though unsure on that.
However, that part is a pretty huge and obvious bug.
As for the centering issues -
No, FD haven't said "This is a regression" but they have said they realise there are problems with FSS and have passed them on to be resolved - and said this when the main complaint appeared to be the re-centering into the "wrong" position (the original message from frontier was in this thread in which the OP only mentioned the minor graphical problem that I sometimes get)
The reason I say it is a regression error, is because I played during the beta when the FSS was being tested, and before release, they got feedback from the playerbase wanting it to be changed, and then they changed it, and said this was the new design intent. (I personally see the merit in the way it worked before this change, but understand the want to have it not behave the way it is currently)
The current behaviour is exactly as it was during the beta (regarding the re-centering only)
This coupled with seeing many "regressions" after patches in the past (understandable with such a huge interlinked and complex code base) leads me to believe it is indeed a regression to previous behaviour which existed during the beta, and was then changed.
