4949 - [PP]Refresh problem when using Page-Up,Page-Down, Up and Down in content window

Status: VERIFIED DUPLICATE of bug 4299

(Core Graveyard :: GFX, defect, P3)

Description

[Andreas Otte]

(Linux-Build, current tree)

Using Page-Up, Page-Down, Up and Down-Keys in apprunner and viewer
gives really ugly results. The window content becomes highly distorted.

With Page-Up and Page-Down this usually happens when reaching bottom
or top of the HTML-Page, with Up and Down it happens all the time.

For an HTML 3.2 example look at http://www.begriffslogik.de.
It heavily uses tables.

Other than the thumb not moving, I don't see any problems with this page. Can you
provide more information or verify with latest builds? Ramiro, would you check
this on Linux?

This happens on my linux box: The page is displayed properly, but if you start
using "down", it updates the content window about ten pixels or so with each
key-event I guess. But the content is not properly moved, so it breaks,
displaying parts of the just moved content many times. Same happens with up and
in lager portions with page-up and page-down. Hope this helps. I have seen this
on many pages I have visited with mozilla.

It seems to be a refreshing problem of the content window. Some time it takes
several seconds before a refresh happens when using the keys, or some other
action is necessary like resizing the window, opening another window, switching
focus, something like this. After the refresh all is okay.
