67521 - Switching tasks may corrupt browser window contents

Status: RESOLVED DUPLICATE of bug 66034

(Core :: Layout, defect)

Description

[Warner Young]

In the last couple of weeks, I've been seeing an occasional problem where 
switching back and forth between multiple browser windows sometimes causes one 
of the windows to be corrupted: usually the scrollbar disappears completely, and 
the actual HTML content is sometimes corrupted, too.  If you click where the 
scrollbar *should* be, it repaints itself and works.  Forcing the browser to 
repaint (e.g. drag it mostly off-screen and back) will restore things.

Doesn't seem to be any particular URL, and I've seen it happen on Modern and 
Blue themese.

I just noticed this today with the today's build on win32 (win2k).  I loaded a
.jpg in one window.. I switched back to the original window.  On switching back
to the jpg it has disappeared and I simply had a white blank window.  No amount
of switching / clicking could make it return (image fit the screen so no scroll
bars).  Resizing the window made the image appear again.

could this be the same as http://bugzilla.mozilla.org/show_bug.cgi?id=67215

Bug 67215 doesn't sound *exactly* the same, but it's similar enough that, yeah, 
I'd guess this is most likely a dupe of the other.

My bet this is a dupe of bug 66034 it is consistant with what I see in that bug.

Comment 6

[Warner Young]

Keyser, you're right.  It does sound like bug 66034.  I didn't find that because 
I was searching for the word "corrupt."  This should be marked as a dup, then.
