@ivylsaid:The test is checking how many cursor updates we can fit between vblanks, and treating that as a baseline. Then it does 30 flips and checks whether we fit expected (num_of_flips * baseline / 8) amount of cursor updates. The check is done 50 times.
We fails this check but yet the cursor refresh rate for each failure is well above 1k (per 30 flips) and there are really no sense in having mouses with refresh rates higher than 1kHz.
The customer impact is low.
The test needs some rethinking and possibly updated pass criteria.@mupufsaid:(In reply to Arek Hiler from comment 18)

Anusha, please update the test to clip the wanted refresh rate to 1kHz, anything above above is useless and just adds noise.
