Description User image Mike Schuette 2001-10-15 20:22:11 PDT
There seem to be a lot of unconfirmed bugs being filed lately from users
complaining of corrupt rendering, ranging from a few minor blemishes to complete
chaos.  All of them are using ATI videocards.

I'm filing this to keep track of these bugs, and hoping someone will be able to
confirm/pinpoint or deny this problem.
Comment 1 User image Mike Schuette 2001-10-15 20:25:32 PDT
Adding meta, setting initial dependencies to 101634,101749,102363,102401.
Comment 2 User image Alex Vincent [:WeirdAl] 2001-10-20 20:04:34 PDT
What's going on?  I've seen this bug a few times in the UNCO list... but the
dependencies have been added twice and removed twice...
Comment 3 User image Mike Schuette 2001-10-20 22:35:21 PDT
First time the dependencies were removed (and re-added), I mid-air'ed with
myself, having the bugs open in another window.

This time, I have no clue ...  I blame Bin Laden.
Comment 4 User image Mike Schuette 2001-11-02 02:07:33 PST
This appears to be win98-specific, as the reporter in 102363 commented that the
problem went away after upgrading to windows 2000.

I do realize that this is probably a driver issue, and won't get "fixed", but
would like to see this qa'ed to the point of having either a definite known
issue or not.
Comment 5 User image Matthias Versen [:Matti] 2001-11-04 04:29:21 PST
This is a tracking bug -> tracking
And you filed this tracking -> assigned to you
(BTW: ATI should fix their drivers)

Shot of one such diseased computer

 Added here is a pic of my Mozilla {Build ID: 2002022103} on Win98 with a
kruddy ATI RAGE LT PRO AGP 2X card @ 1024 x 768. Note the top part with the
MozillaZine icons. FYI, ATI users have had to put up with this weird picture
display (which gets worse when you start scrolling) since before Netscape 6.0
times, probably since the inception of this project.

 I think the chrome problem (surely you can see the crapped-up Nav Bar, sidebar
and scrollbar, also the loading bar) is unrelated to this, and is happening to
me only so just look at the web content (but anyone who knows what's wrong with
chrome could always help me out with that too...:) and ignore the frontend.

Another such shot in Classic

 Have a look at the first attachment ("Shot of one"). See the weird stuff on
the MozillaZine .gif? Well it looks like the ONLY problem here with these old
ATI cards on win98 (in other words on most of the computers Compaq has made
recently) is rendering .gifs. Every time I see this problem (which is far too
often to be ignored), the problem appears to be with .gifs. Now I don't know
much about how .xul is implemented, but aren't buttons in themes in .gif
format? Because when you see attachment #2 [details] [diff] [review] ("Another shot"), the frontend
buttons aren't rendered right.

 By the way, the same rendering problems with .gifs and with the frontend come
up on another computer I have running Win98 and an even older ATI card (same
Mozilla build).

Proposed relnote: Using Windows 98 with some ATI graphics adapters will result
in corrupt inline image rendering on web pages.

Comment 10 User image Aaron Greenspan 2002-05-27 22:22:22 PDT
With an ATI 32MB RADEON SDR video card from late 2000 that came with my Gateway 
machine, I have experienced similar problems (with transparent GIFs, 
scrollbars, and scrolling in particular). However, I just noticed that 
Gateway's "latest drivers" are far from the actual latest drivers at, 
so I'm going to upgrade as soon as possible. You may want to advise users with 
similar problems to bypass their OEMs' support sites and go straight to 
in order to resolve their difficulties. These bad drivers also cause problems 
with other programs, including Photoshop, so I would hope that by now, ATI has 
heard about and fixed them.
Comment 11 User image Ian Westcott 2002-05-29 07:58:43 PDT
I have been tracking this problem for a while, I'm glad to hear that there are 
other people out there who see it.  
I opened but 121778 once upon a time (see information and attachments there) 
and it was later marked as a duplicate of but 94494, which is still open.  
Adding 94494 to dependency.  

I first saw the problem on an NEC computer running Win98 with an ATI RAGE PRO 
TURBO at 800x600x32 bit, which fits the hypothesis.  I can confirm that the 
problem is only with transparent .gif's (although transparent PNG's may be 
problematic as well, I'm not sure.)
Comment 12 User image Andrew Hagen 2002-05-29 14:33:25 PDT
Upgrading the driver is not necessarily feasible. On a system with an ATI Rage
Pro LT, I upgraded from the May 1999 driver to the "alternate" driver. That
solved the display problems covered by this bug. Then, a month later the system
became unstable and wouldn't boot into the Windows GUI. It was difficult to
restore the original driver. The machine is now using the old driver and is stable.
Comment 13 User image junk 2002-06-04 23:27:03 PDT
I had a problem as shown here:

Sometimes bottom is black, or has bit of other tabs, etc.

I just upgraded my ati rage 128 xpert driver here:

and now is fine again. I did upgrade to directX 8.1 first, but that did nothing.


Was driving me nuts, but there's the solution for me anyway.

This report now appears to be affecting Windows 2000, too. Changing summary to
reflect that.

Comment 23 User image franCk 2002-06-15 00:36:07 PDT
I have observed a similar problem (resized image were corrupted - see bug 151081
and attachment there) and it was solved by using the 'alternate driver' provided
on the ATI website (as suggested by comment 13).

May I suggest that this bugs, and the similar ones, are not dupped when their
summary is different? Apparently the problem with the ATI driver can have
multiple effects, and also the cause is the same, it is not obvious to analyse
that when you're a normal user... thus using bugzilla you'll never check for
'ATI video card', and 'rendering problem' is not specific enough to be of any
help (Did you ever use the word 'rendering' in a search? At least the summary
should have the word image, no?!)
In the other hand please add the bug 151081 in the dependancy list...
OK if you feel I'm wrong with my idea of letting a bug open which is a duplicate
and not even a Mozilla bug, tell me :-)
Comment 24 User image franCk 2002-06-15 00:54:31 PDT
BTW, the information is available in the release note for 1.0 as:
"Using Windows 98 with some ATI graphics adapters will result in occasional
corruption of inline images as rendered on web pages. This is an ATI graphics
driver bug. (Bug 122445)"

You notice that there is a bug here: the referenced bug 122445 has nothing to do
with this issue, it should be this bug 104992... but the link is right, when you
click on it you're brought here!

OK, I'm sure this message is close to spam, but I don't know how to contact the
relnote guys otherwise... Sorry!
Comment 25 User image Michael Bruck 2002-06-18 10:20:16 PDT
I have a similar problem with an ATI RAGE 128 PRO, Win 98 SE, ATI driver
06.34-CD16-1C or 4.12.6292.

My Mozilla 0.9.7 2001122106 doesn't show this problem while 1.0 messes up our
homepage under

The pages heavily uses PNG as table backgrounds.

See comment 12 for a brief note about a stability problem with one of the new
ATI drivers. 
Comment 33 User image Steven Neil Groginsky 2002-07-11 15:47:54 PDT
I'm using win98se and an ATI 2x AGP 8 MB Rage XL (98 Xpert) card.  I have
observed complete distortions of images near the top of the page several times
which are mostly noise, but with some vertical darker lines I saw as layers -
reminded me of a broadcast tv where the vertical was out, except of course it
wasn't moving.

I think AGP boards are very tricky and some do some "dirty hardware tricks" to
maximize efficiency.  There are settings in the BIOS (CMOS) for several
different functions and you can set the video via all sorts of different
software functions.  Of course, you're supposed to get a uniformly good result :)

(scrollbar artifacts) with my ATI RAGE MOBILITY-M PCI in spite of installing the
latest recommended driver from IBM Update Connector.
Comment 37 User image Steve Hill 2002-08-22 16:50:54 PDT
I'm not sure if this is what this bug (#104992) is related to, but on an
E-Machine 667Mhz, with Intel 82810 Graphics Controller connected over the PCI
bus (i.e. not ATI) and running Windows ME, when I use the scroll button on a
page, some typed lines at "squished" by what appears to have been a dropped
raster, while others are "tall" with an added raster line.

It is only a minor annoyance, easily corrected by a page-up/page-down, but
figured that I ought to report it for a better Mozilla.

Comment 38 User image Daniel Herring 2002-09-23 09:00:50 PDT
Bug #96803 also discusses this bug.
Over there, dropping the bit depth from 32 to 24-bit seems to fix many people's

Is there any way this information could make its way into the release notes?

On comment 31 and 32, I'm using the latest stable ATI driver for Rage Pro LT,
with 24 bit color. I haven't seen graphics corruption since I switched from 32
bit to 24 bit. I can confirm that using 24 bit color is a workaround.

I solved this problem by upgrading from ATI RAGE LT PRO
driver version 4.10.2456 to 4.11.2560.

The system in question is a Compaq Presario 5610 with a
FP500 (flat panel) monitor.

More information about the drivers is at:
Comment 46 User image Andrew Hagen 2003-03-05 09:11:59 PST
Re: previous comment. That's the driver I was talking about in comment 12 when I
warned of the driver causing system instability. Incidentally, this system is a
Compaq Prosignia 150. When the instability problem reared its head after several
largely uneventful weeks, my system would not boot. I had to install a different
driver. After great time and effort, I able to install the older driver again.

I strongly recommend using the older, stable driver for Rage LT Pro. This bug
(rendering problems) can be avoided by using the older driver and setting the
color depth to 24 bit, and not 32 bit.
Comment 47 User image George 2003-03-05 09:58:47 PST
I "solved" this bug by selecting TrueColor (24 bit) 1280 x 1024 with Rage IIC
AGP (Mach64GT chip) Driver 5.24-CD3 on a Win98 machine

More ATI trouble.

I'm using an ATI XPERT 98 RXL AGP 2x card with driver v5.0.2195.5013.
OS is Win2k SP3.

Till now I didn't have any problems. But the current nightly 
(BuildID 2003032808) does not render the right and bottom edges
of frames at all. 
When scrolling, the whole frame becomes a mess.
The bug occurs in 6, 16 and 32 bpp modes.

I uploaded screenshots at:
