Please ignore that, I wasn't really thinking when I wrote this.
Unfortunately, I cannot reproduce the bug on any build of Emacs. Please
instrument the following code around line 21053 of xterm.c as follows:
/* See the comment on top of x_cache_xi_devices
for more details on how scroll wheel movement
is reported on XInput 2. */
delta = x_get_scroll_valuator_delta (dpyinfo, device,
i, *values, &val);
values++;
if (!val)
{
other_valuators_found = true;
continue;
}
printf ("%g\n", delta); <=== add this instrumentation
if (delta != DBL_MAX)
{
and show what is printed when you try to scroll using the mouse.
Thanks.
