Wouldn't it make sense to change the buffer logic in the input layer
that in the case of a buffer overrun the head gets pushed forward to the
next SYN_REPORT?
One symptom I witnessed with the bug was, that I got partial reports,
which especially in the case of a multitouch report (A-Type) creates
false release-events. This would be solved by the head-forwarding.
(one could even think about more fancy stuff like combining relative
events and keeping track of the absolute events, but this seems a bit
like overkill)
Thanks,
Simon
