           Summary: Backbutton doesn't redraw page containing form (in which
                    password was filled)
           Product: WebKit
           Version: 526+ (Nightly build)
          Platform: PC
               URL: http://www.festiwal.nysa.pl/a.php
        OS/Version: Windows Server 2003
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: krzyko at gmail.com


Tested on r35615 as well as on 3.525.21. I've put a testcase on the given URL.

When I fill the login form and click "Login" button and then click the browser
back button, the screen isn't rendered correctly (the after login page remains,
with screen corruptions added from the login form page). It's also impossible
to click on anything: the after login page link doesn't work as well as login
form itself.

In this situation the screen is redrawn only when I tabulate three times to
focus submit button. Then, also resizing browser window or changing browser
font size redraws screen correctly.

This problem occurs only when the password input element is filled, when it is
left blank the browser back button after submitting the form will redraw the
page correctly.
