Description of problem: Under XWayland, touchpad scrolling moves in discrete steps. This is covered in the upstream bug crbug.com/712737. To summarize, X clients that use high resolution scrolling will lose the first discrete mouse wheel tick after focus is gained. This is a general problem of X, see https://bugzilla.gnome.org/show_bug.cgi?id=750994. Chromium has a heuristic that tries to work around this, but on Fedora the heuristic doesn't work on X and breaks hi-res scrolling on XWayland. Until a solution is found upstream, Fedora Chromium would benefit from a patch that reverts https://crrev.com/b794998819088f76b4cf44c8db6940240c563cf4 Version-Release number of selected component (if applicable): chromium-57.0.2987.133-1.fc25.x86_64 How reproducible: Always. Steps to Reproduce: 1. Use libinput X input driver or Wayland. 2. Scroll with a touchpad. Actual results: Under X, the scrolling is high resolution but mouse wheel ticks are still lost. Under Wayland, high resolution scrolling doesn't work. Expected results: High resolution scrolling everywhere. (And maybe no lost mouse wheel ticks.)
