| 1207 | * Windows 8 specs says 2 things: |
| 1208 | * - once a contact has been reported, it has to be reported in each |
| 1209 | * subsequent report |
| 1210 | * - the report rate when fingers are present has to be at least |
| 1211 | * the refresh rate of the screen, 60 or 120 Hz |
| 1212 | * |
| 1213 | * I interprete this that the specification forces a report rate of |
| 1214 | * at least 60 Hz for a touchscreen to be certified. |
| 1215 | * Which means that if we do not get a report whithin 16 ms, either |
| 1216 | * something wrong happens, either the touchscreen forgets to send |
| 1217 | * a release. Taking a reasonable margin allows to remove issues |
| 1218 | * with USB communication or the load of the machine. |
| 1219 | * |
| 1220 | * Given that Win 8 devices are forced to send a release, this will |
| 1221 | * only affect laggish machines and the ones that have a firmware |
| 1222 | * defect. |
