Last modified: 2005-10-31 17:00:50 EST
Description of problem:
Since upgrade from 8 to 9. The screen doesn't refresh properly. When I first
login I get a block under the cusor on the desktop or wherever the cursor is.
Then if I click and hold the scroll bar down in Mozilla 1.3.1 and go over the
main portion of the screen I get multiple cursors and snipits of the scroll bar
left on the screen where the cursor had been. I also get unpredictable images
under the cursor when just moving the cursor. None of these issues existed
prior to the upgrade to RH9
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Follow steps in description
A clean properly refreshing screen, with out artifact.

This shows the mozilla behavior
You haven't mentioned anything about what actual video hardware you are using.
It is very unlikely that if this is a bug, that it happens for everyone on
all hardware. Please provide full details of your system, and attach your
X server log and config file.
Also, does this only occur with mozilla, or does it occur with other apps.
Please test many applications and list the names of some others that show
this (if any).

/proc/pci, X logs, X config file
Here is the requested info included in one file.
Like mentioned above when I first enter the desktop (login) whereever the cursor
is I get a square about 4cmx4cm. This happens on the desktop or whatever
application the cursor seems to be over at login. Mozilla so far is the only
app that I get the wierd scrolling behaviour.
I also just noticed this behavior. When an application changes screens I also
get the 4cm square under the cursor. I will try and capture this for you.
Individual uncompressed file attachments only please, so they can be viewed
right in the web browser with a click.

Ok, this is probably a driver bug related to Xcursor changes. It's odd it
only happens in mozilla though. Can you try using the following option
in the Device section of your X congig file:
if that doesn't change things, try
If still no go, then try
Report back which if any of these options make any difference, and we'll
troubleshoot further to try and narrow the problem down.
I also notice another bug in the i740 driver in your log file, which I'll
fix in the next build:
Symbol vbeFree from module /usr/X11R6/lib/modules/drivers/i740_drv.o is unresolved!
blizzard: Any reports of this nature against mozilla on other hardware?
The only option which had any effect was the noaccel. So far it seems to have
fixed the problem.
Just to clarify the issue. At login I would get a 4cmx4cm splotch under the
cursor. I have also notice issues with open office, including the screen
freezing and not scrolling and refreshing.
