Applies to the Lenovo T420s Touchpad on Ubuntu 14.04 too. So no "feature" of newer systems.
Encountered the bug about one week ago. Also applies to the current Chrome unstable dev channel. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to webkit in Ubuntu. https://bugs.launchpad.net/bugs/1598519 Title: regression: page scrolling jumps to top of page spontaneously Status in chromium-browser package in Ubuntu: Confirmed Status in webkit package in Ubuntu: Confirmed Bug description: I switched to chromium-browser from Google Chrome when, 1-2 months ago, Chrome began to misbehave on all pages. It spontaneously jumped to the top of the page when I continue scrolling downwards (using a touchpad). As of a July 1 update to chromium-browser:amd64 (50.0.2661.102-0ubuntu0.16.04.1.1237, 51.0.2704.79-0ubuntu0.16.04.1.1242) chromium-browser now has the same bug! Chris Down, in comments below, says the bug is affecting most webkit-based apps. He and I are both on higher-end Lenovo thinkpads (T450s, T460s), (and I believe this also affects T410s -- to confirm)). To reproduce this, I scroll half-way down a page (using a touchpad?) and then click on something (e.g. blank space, which has no effect, or ctrl-click on a link to open it in a new tab) with a mouse button. Next, as soon as I touch the touchpad to continue scrolling, the page jumps to the top. Makes browsing near impossible. Very frustrating to have this bug arrive at this browser after I already left Chrome (whose latest version on Ubuntu also still has this bug) to avoid it.
