At least opposite field "ghost" image should be nearer the actual mouse image when moving the mouse fast.

Could you please elaborate a bit on how AmigaOS handles mouse cursor in interlace mode? IIRC on real Amiga it was as fluid as in non-laced mode?

Problem is interlace itself.
It can only look correct in "fields+" mode where alternate lines are blanked. Without it comb artifacts are visible (both fields are visible simultanously when in real interlace they have 1/50s difference)
You can see exact same effect when running any demo that has interlace graphics and horizontal scroller. Scroller will look horrible without "fields+".
(for example Shed Tears by Ozone). But it can flicker also badly if refresh rate is not in sync with monitor = vsync or variable sync monitor required.
In WB (also works in some programs that take over the system) you can "fix" it by ticking "Remove interlace artifacts" option (=emulate frame as progressive by basically emulating both fields at the same time)
