libinput-list-devices output

I have an ASUS P53E laptop with a Synaptics touchpad.

libinput-debug-events recognizes the 3-finger gestures, but prints an error on each update:

libinput error: libinput bug: Event for missing capability CAP_GESTURE on device "SynPS/2 Synaptics TouchPad"

Both Wayland and Xorg are equally affected.

I use Debian Sid with libinput 1.2.4. (1.2.4-1 package)

The gestures work fine if I workaround the capability check by making it always return 1, so the hardware is indeed capable to do that.

Please attach the output of evemu-record for one of these gestures, thanks.

Is this problem fixed on 1.3.0? Because I'm getting the same error

Sorry, I have seen that the commit was after the 1.3.0 tag. Thanks!

Just pushed out 1.3.1, that contains the fix.
