Hey, I'm not sure, but something seems to have changed two-finger-scrolling on Synaptics touchpads in the latest snapshots.
My snapshot is from June 2nd. The following is what happens: In Chromium, if I click somewhere and subsequently scroll the website using two-finger-scrolling, it scrolls more units (e.g. to the top/bottom of the page) and sometimes even in reverse. I can't quite extract the pattern, yet. Can anyone confirm this? Is this Xenocara or Chromium related?
