With pixel-scroll-mode on, when pixel-resolution-fine-flag is nil (the
default), I cannot get Emacs to scroll up by "just a few pixels",
however small my movement on the touchpad. Emacs always waits for
"enough movement" to scroll up a complete line, although the *animation*
is indeed done pixel-by-pixel (as opposed to line-by-line when
pixel-scroll-mode is off).
On e.g. Mousepad (XFCE's text editor), if I move "just a bit" on the
touchpad, the display moves by "just a few pixels", i.e. less than a
full line. FWIW setting pixel-resolution-fine-flag to 1 seems to allow
Emacs to do the same.
(I hope I understood Alexander's problem correctly; apologies for the
noise if not)
