title="RESOLVED FIXED - RFE: pointer acceleration needs to take resolution into account"
href="show_bug.cgi?id=79056">bug #79056</a> but for mice.
The pointer acceleration uses device-specific input data to apply acceleration.
That data is resolution-dependent, the deltas provided by a low-resolution
mouse are less than the ones provide by a high-resolution mouse.
This causes high-resolution mice to max out the pointer acceleration quickly,
effectively running at maximum acceleration at all times.
The main difficulty here is: devices do not allow detection of the actual
resolution, maintaining a database of all devices with a non-standard
resolution is going to be difficult. Even unclear if it's possible at all, what
if devices share USB IDs? Good suggestions welcome.</pre>
