           Summary: [GTK][AC] Resizing the window doesn't always update
                    the visible rect
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW

I'm using Debian's 2.22.0

Not sure if it's the same case as the old https://bugs.webkit.org/show_bug.cgi?id=115096 but sometimes I enlarge a window and the new space for the visible rect is just filled with a grey color but the contents of the web page are not painted there.

I still haven't found a reliable way to reproduce it, but you just need to resize the window several times (perhaps not continuously but not sure) and the problem will eventually show up. I'm adding the [AC] tag because I suspect that's the culprit of the visual artifact I'm observing.
