No, the bug shows even if no point motion takes place. Here is my attempt at detailed reproduction instructions: 1. Start Emacs. Switch to a new buffer. 2. C-u 100 a 3. C-u 200 M-x duplicate-dwim RET 4. If necessary, resize the frame so that the lines wrap. 5. C-x x t 6. M-x pixel-scroll-precision-mode RET 7. C-u 100 M-g g 8. C-l (to center point on screen) 9. C-e Now try scrolling gently up/down using the trackpad, mouse wheel or = similar device. Expected: buffer scrolls smoothly in both directions. Observed: buffer scrolls smoothly in one direction but not the other. It would be useful if someone would try reproducing this bug on = platforms other than macOS as well, to help us understand if the bug is = specific to that port. > Thanks. You are welcome.

I thought I replied that this is user error: pixel scrolling to a position that requires moving point will reset hscroll unless auto-hscroll-mode is off, as it should be if moving point to the start of a line is not meant to reset hscroll, whether through scrolling or otherwise.
