End of the day and I have better news now:
The first prototype of client-side vsync is working well and I'm hopeful
to get it into Mir 0.26. With some luck that will solve the
incompatibility between Qt's input resampler logic and our nested
architecture. So then if Unity8 is able to use Qt's input resampling,
Mir won't need that feature any more (we just declare it's now the
toolkit's job to resample touch events).
Once Mir doesn't need to provide input resampling any more, the failing
test case here will be removed along with the feature.
** Changed in: mir
Assignee: (unassigned) => Daniel van Vugt (vanvugt)
** Tags added: input performance
