I already explained why the viewport size has to be changed when the location bar moves - content that's fixed to the viewport (CSS position: fixed or scrollbars) will be positioned incorrectly and could be outside of the webview if it's not. Not resizing the viewport is not going to happen.
Our browser behaves exactly the same as Chrome on Android here - in fact, we use the same code for controlling the location bar position (it's controlled by Chromium's renderer compositor, not the browser). This problem doesn't manifest on large Chrome tablets because the location bar is always displayed (at least, it is on my Nexus 10). A quick check of the source code for Chrome/Android confirms that it's always displayed on larger screens (where the smallest dimension is greater than 800 DPs https://chromium.googlesource.com/chromium/src.git/+/6ab9853acfbfae3e598004776c1d120805956038/chrome/android/java/src/org/chromium/chrome/browser/tab/TopControlsVisibilityDelegate.java#31 https://chromium.googlesource.com/chromium/src.git/+/6ab9853acfbfae3e598004776c1d120805956038/chrome/android/java/src/org/chromium/chrome/browser/device/DeviceClassManager.java#162 On my Nexus 7, the location bar does hide but this problem doesn't manifest presumably because it gets the mobile UI which expects this behaviour. On both my Nexus 10 and Nexus 7, Chrome gets slightly different layouts of the mobile UI for Google Plus. Our browser on the M10 gets the standard desktop UI. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to webbrowser-app in Ubuntu. https://bugs.launchpad.net/bugs/1575191 Title: plus.google.com re-layouts horizontally when the top bar shows/hides Status in Canonical System Image: Confirmed Status in Oxide: Invalid Status in Ubuntu UX: New Status in webbrowser-app package in Ubuntu: New Bug description: Some sites have a menu bar at the top, which appears or disappears depending if you scroll up or down... the presence or absence of this bar causes the browser app to change it's scaling, and this means that scrolling up/down while browsing results in the device continually re- rendering as it re-scales the page...
