Description hello 2016-07-11 04:52:58 UTC

If you initiate a multitouch tap (two or three fingers), the fingers in the exclusion area are not registered (), this also happens with two finger scrolling, if one finger starts in the exclusion area, pointer movement happens instead of scrolling.

There are two options to fix this, one would be if there are any other fingers registered, exclusion are should be disabled,OR an option to turn palm detection and therefor exclusion areas off altogether because at the current state gesture and taps are not registered and it is very annoying.

Arch linux on UX305FA, using libinput v1.3.3

This is when scrolling exclusion area

For some reason when playing it back, it works just fine but when recording, it doesn't scroll at all and just moves the pointer.

Unless you have libevdev 1.5.0 or later installed the cause is probably that the resolution isn't set correctly when you create an evemu-device. Does replaying through the touchpad itself work?

I knew this sounded familiar - already fixed ;)
