Right, thanks. Could you please run Emacs underneath a debugger (GDB or
LLDB), and see whether or not this code around line 7342 of nsterm.m is
ever hit:
CGFloat delta = [theEvent deltaY];
/* Mac notebooks send wheel events with delta equal to 0
when trackpad scrolling. */
if (delta == 0)
{
delta = [theEvent deltaX];
if (delta == 0)
{
NSTRACE_MSG ("deltaIsZero");
return;
}
emacs_event->kind = HORIZ_WHEEL_EVENT; <================
}
else
emacs_event->kind = WHEEL_EVENT;
emacs_event->code = 0;
emacs_event->modifiers = EV_MODIFIERS (theEvent) |
((delta > 0) ? up_modifier : down_modifier);
when you try to scroll left or right with your mouse while
pixel-scroll-precision-mode is enabled?
