I see the same as Evgeni here on GTK+ Version 3.8.8:

    emacs -Q
    M-: (setq frame-resize-pixelwise t) RET
    M-x make-frame-command RET
    Switch to new frame
    M-: (set-frame-parameter nil 'bottom-divider-width 10) RET
    M-x split-window-below RET

As before, the bug is not observed.

    Drag the window divider up a few pixels (but less than one line)

As before, the bug is observed.

But with

    emacs -Q
    M-: (set-frame-parameter nil 'bottom-divider-width 10) RET
    M-x split-window-below RET
    Drag the window divider up a few pixels (but less than one line)
    Observe bug
    M-: (setq window-resize-pixelwise t)

The bug is no longer observed. Note that I didn't move the divider after
setting window-resize-pixelwise, the bug was immediately no longer
manifest.
