Description

16 years ago
If one has a page with several frames with respective scrollbars (x and y), and
if one uses the horisontal scrollbar in one frame while another frame is still
loaded/rendered, part of the scroll bar will be painted just above the URL input
field.

Steps:

0. Simulate or work on a display of 1024x768 (to get the scrollbars)
1. Load forthcoming frameset attachment
2 [details] [diff] [review]. Click on the "Live Feed" buttons in two or more frames
3. As soon as a live feed is rendered, await another live feed to start render,
and then adjust the java content (the live feed) horisontally so that it fits in
the frame.
(4. Repeat the procedure by changing "rooms" if this isn't immediately visible)

Result: horisontal scrollbar is duplicated above URL input field. See
forthcoming screen dump. This is always reproduciable.

This is build 20002-08-21-09, but it applies to all Mozilla builds.

The painting problem. This sticks throughout the session.

Testcase no longer works. Niklas, please update it, and also try to use
non-pornographic material, please. Thank you.

Marking WFM - no communication from original reporter for ten months now.

Please reopen with new test case if you are still seeing this bug.
