Created attachment 1059895 [details] 2 scroll events Description of problem: I recorded 2 scroll events. In the ememu-record file, I see touchpad events from 0-0.85s and from 1.83-2.58s. However when I play back with evemu-play, only the first scroll appears to occur. Version-Release number of selected component (if applicable): libinput-0.21.0-1 How reproducible: Every time you play the attached file Steps to Reproduce: 1. Get libinput device for Elan touchpad 2. sleep 1; evemu-play <touchpad device> < two-finger-scrolling-small.events 3. Quickly alt-tab to chrome Actual results: scrolls down a few lines after 1s Expected results: scrolls down a few lines after 1s, scrolls down a few more lines after 2s Additional info:
funny timing, I observed that yesterday too. Note that evemu offsets the events to a 0 delta, so if you start a recording but don't touch the device for 10s, the replay will still start immediately. This is why the alt-tab approach to testing is a bit risky, you're likely to always miss the events. Better to use sleep 2; sudo evemu-play .... That aside: it is definitely a bug, fix is on the list, will feed down to Fedora soonish: http://lists.freedesktop.org/archives/input-tools/2015-August/001193.html

I'll do a git snapshot for fedora to fix the bug.

Is this supposed to be fixed? Playing back the attached events file with evemu-2.2.0-2.20150818giteba96a4.fc22 still only scrolls once
Created attachment 1066061 [details] Two finger scrolling I'm seeing other incorrect artifacts. The attached recording was made with libinput-0.99.1-1.fc22, and played back with the same. When I recorded it, I performed a two-finger scroll up and down in a chrome window and it scrolled many lines up (then opened a right-click menu). When I perform it with evemu-play, it only scrolls one line up.
I just took that recording and re-recorded it through a virtual device and the output is almost identical, save for a few timestamps that are off. Though by the end of the recording the time dilation is less than 3ms, so that shouldn't hurt (and it's mostly unavoidable in any case). Can you confirm this on your box? run evemu-record and replay the sequence and then diff the two files. also, fwiw, the libinput version won't affect the evemu recording, they are independent. see the diagram at the bottom of http://wayland.freedesktop.org/libinput/doc/latest/reporting_bugs.html
