Bug 160503 – [GTK] Background-color not filled after multi-touch zoom

• Status: RESOLVED
• Resolution: WORKSFORME
• Component: WebKitGTK

[Jan]

This is something I can't reproduce since I don't own a touch-screen, but a user of my application reported:
After using multi-touch gestures to zoom the webview, the background color (http://www.valadate.org:8000/#!api=webkit2gtk-4.0/WebKit.WebView.set_background_color) is not filling the whole webview. It is only stretches as far as the view-port of the webview was before zooming.

This issue has also been raised in the epiphany (Web browser) bug reports, do take a look:
https://bugzilla.gnome.org/show_bug.cgi?id=766916

The perspective is different though- why should a webpage be zoomed out at all beyond "fit" (via pinch-to-zoom)? I understand that this is not traditional zoom, but ipad-like static zoom. Rather than filling in "background" color, prevent zooming out beyond 100%?

The problem is even more pronounced with fullscreen html5 videos. In that case boot zoom in and out beyond 100% are undesirable (because fullscreen). Should that be filed as a new bug?

*both* zoom in and out are undesirable

Yes

Is it still a problem? I cannot reproduce it with touchpad in 2.24.1 and in trunk, it doesn't allow to zoom beyond 100%.
