While normally not a big issue some sites (especially modern RIA web applications) process this resizing with heavy operations, especially since the default behavior is animated 1 second display/hide, which leads to numerous resizings It would be better if the tool-bars would hover above the page content partially hiding the top-part of the page, which is reasonable. This would make modern web-based RIA applications perform better in full-screen. Reproducible: Always Steps to Reproduce: 1. Open a modern RIA framework demonstration, such as http://www.smartclient.com/smartgwt/showcase/. 2. Switch to full screen with default settings (auto-hide over 1 second) 3. Point to the top screen edge to display the tool-bars. Actual Results: The tool-bar shows, the page gets resized, with a very choppy animation. Expected Results: The tool-bars should float-in hovering over the page without any visual changes in the page. This behavior should be changeable by the user, at least with a preference item.

I guess this should really be directed to the UX/UI team. It's a request for a change, not necessarily an enhancement, since others will most certainly disagree with the proposed change. Adding "uiwanted".

>uiwanted We probably want to change to a model where in full screen the UI is either pinned (always shown) or not pinned. For the case where it is not pinned, I'm pretty sure i'm in favor of it overlaying the content area instead of pushing the content area down, but I should debate this with the rest of the team before we can completely sign off on the change.

This is already the case (right click the toolbar and deselect "hide toolbar buttons" while in full screen mode). Either way, I'm confirming this bug so that consensus can be found and made here.

This bug suggests an overlay instead of a push down. Examine Chrome behavior for an overlay-like behavior (when cursor hits top of the screen, the user gets a small prompt telling them to press F11 to show the toolbar). Consider also bug https://bugzilla.mozilla.org/show_bug.cgi?id=727099 as an alternative (user customizable delay before showing toolbar).
