Good catch. This must have blocked a lot of motion events too, since we only
report motion events on SYN too and only the most recently received slot then.
I think this should fix this bug (ie what Rusty reports), but I think it's
different from Arties problem in <a href="show_bug.cgi?id=67563#c4">comment 4</a>. Arties case is where we have a
old-fashioned single-touch touchscreen that only reports BTN_TOUCH for touch
up/down and ABS_X/Y for position. Patch applied, but we have to keep looking
for the single touch problem.</pre>
