            Bug ID: 155229
           Summary: [GTK] Artifacts when using web view background color
    Classification: Unclassified
           Product: WebKit
           Version: WebKit Local Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Keywords: Gtk
          Severity: Normal
          Priority: P2
         Component: WebKit Gtk
          Assignee: webkit-unassigned at lists.webkit.org

This is easy to reproduce by using the MiniBrowser in editable mode, try something like this:

MiniBrowser --bg-color="rgba(255,0,0,1)" -e

Write someting and move the cursor or select text, you will see that some areas are not repainted at all. This is because when using a web view color, we fill with the color every rectangle updated by the web process, but we should always fill the entire backing store before rendering the actual contents on top.
