Bug Description
Clients can't get high frequency input in Unity8.
Using native (non-nested) Mir servers, clients can get the full speed input stream if they so choose (MIR_CLIENT_
However in Unity8, because it is a nested server, the client no longer has the option of getting this high frequency input.
Examples of clients that utilize high frequency input for improved visual quality:
mir_
mir_
You may also want to experiment with those using ultra-high frequency input by adding a kernel parameter: usbhid.mousepoll=1
This is a tricky problem because for touch at least we do want the input stream to be throttled to the display rate from the top level down. Perhaps the answer is to enhance Unity8 to be a full-speed (non-resampled) client and then the clients of Unity8 can then still have a choice of whether they get resampling or not.
