173045 - scrolling creates black out spots ramdomly all over screen

Status: RESOLVED DUPLICATE of bug 104992

(SeaMonkey :: General, defect)

Description

[sam bass]

When scrolling through any of the screens in this web site, black out squares
appear all over the page.  If you do a PAGE UP/DOWN they go away.
Even switching to another screen and back removes the black out squares.
The 'other' browser does not have this problem.

please mention build ID.
What graphic card do you use ? Does it still happen when updating to latest
graphic drivers ?

reporter (sam): can you reproduce this bug with a recent build of mozilla (for
example, 1.3a)? if so, please comment again and give the buildID/version of the
mozilla you are using. if not, please resolve this bug as WORKSFORME. thanks.

I have downloaded Mozilla 1.3a and tested it with the same web pages and it
still act the same. I am running NT 4.0 SP6a 

Scrolling down with the side bar or up/down arrows creates these black squares.
Paging down will remove the black squares.
I see no change.

Sam, are you still seeing this problem with Mozilla 1.3b or later?

I saw this bug before and face it again recently.

I see similar problem relating to scrolling a page (both by mousewheel and
vertical scroll bar, horizontal not tested) From my observation (i.e. feel, no
proof), it seems that sometimes Mozilla has used up "resource" and make render
after scroll not correct. It is true that "page up/down" or switch tab
back/forth will redraw the page correctly.
When this bug happen, I tried to "print screen" and paste the screen to MS Paint
but it said not enough memory to paste the image (but I can see,through W2k Task
Manager,there is over 100MB RAM available.

I am running W2k, and this bug happen to me again since 2003031714.

This has not been fixed in Mozilla 1.3a or in Phoenix .5 .
The black areas only appear when you are scolling new lines into the display
area.  Once there the only way to get rid of them is to PAGE UP/DOWN or a
REFRESH.  As soon as you scroll new lines the black areas reappear.

Not seeing this on 20031123 seamonkey and firebird WinXP builds. Sounds and
looks very much like a driver issue.

Reporter, are you still seeing this? Have you tried to upgrade your graphics driver?
