I can't seem to pull off barrel roll move with a keyboard, anyway. Also, has there been any effort to see how long this has happened, or is it very recent regression?

No.21125 ICEknight Tester Feb 27, 2023, 20:47	But it only happens at a few angles and isn't nearly as pronounced. Have a look at 4:27 at x0.25 speed, this is the most visible it gets: https://i.imgur.com/cUNBjV9.png

Also tried Final Burn Alpha out of curiosity and it seems to behave more like the footage above, the issue only happens sometimes, more briefly and it's less noticeable when it does.
