Core X11 events are used for absolute motion while the mouse is grabbed, as XInput doesn't receive motion events from the master pointer, and the position from the slave devices lags one report behind. However, pointer events emulated from multitouch events can't be filtered out when using core events, as the XInput flags are not passed through. Use the absolute position from slave devices in XInput motion events while the mouse is grabbed and touch events are active to allow filtering out pointer events emulated from touch events. Pointer events in this case may be a report behind the master device, but receiving input from both the pointer and touches simultaneously is not likely to be a common occurrence. |
