Mozilla has problems displaying _some_ images at _some_ bit depths on an 'ATI 3D Rage Pro AGP' card (driver version 5.2.040) under NT. Problem bit depths are: 256 colours : few images bad 65536 colours : most images bad 16.7 million : most images bad True colour : all images OK At the problem bit depths, the images initially load and display correctly, then when they are redrawn (by minimising/maximising window), they disappear and the only thing drawn in their place is what seems to be an image mask (?) in some cases. Attached is a screenshot of the problem at 16.6 millions colours bit depth.

Michael, to confirm, are you quitting Mozilla before making the bit-depth change, and then re-loading Mozilla?

Yes - this I'm quitting before making change. Also, this is latest nightly build. Mozilla on my other computer (with Diamond video card) does not have these problems.

I just checked IE 4.0 and it does not have these display problems. I also checked Communicator 4.7, and it does sometimes have similiar problems, but I could only reproduce them at 16.7 million colours bit depth and there are much fewer images are affected. Also in the Communicator case, refreshing the window seemed to make the problem either go away, or reappear (ie. it was transient).

I can't reproduce this on my Win32 system; Pam, if you also can't reproduce, let me know, and I'll see if anyone has an ATI 3D Rage Pro AGP video card.

Here is another screenshot of the problem (at 65536 colours, 1152*864 resolution) on www.limdep.com/index.htm web page. Notice that only some of the images on the toolbar at left are missing. Maybe it is possible from this screenshot and the actual images from the website, to work out what type of images have a problem displaying and which don't. You can then narrow down what section of the code may have problems. This is NT 4.0 Service Pack 5 system BTW.

|

Ok, I followed my own advise and it seems that the problem is limited to transparent GIF images. Ordinary GIF and JPEG images seem ok.

See Bug #22789 which is related. Using ATI Rage IIC with TrueColor has layout problems.

Eli: What are our chances for finding an ATI 3D rage Pro AGP inhouse? ?maybe check with judge? -p

mjudge doesn't have one, so spammed seamonkey-internal to see if anyone does.

Pushing milestone to 16. Still trying to track down an ATI 3D Rage Pro AGP video card.

I have also have a Rage Pro, and images sometimes render incorrectly for me too. My particular problem is that the images looks fine at first, but when you scroll down, and then up again, it looks ugly. It renders the uppermost few pixels of the image all the time (instead of going on to the lower pixels after the high ones are already rendered) so it looks very ugly. The faster you scroll up, the less times will mozilla render the top of the image, which means that there becomes more pixels per update. If scroll very fast, it looks perfect. I think that I've only experienced this problem at on page, and I will soon upload a page where this problem exist for me. Maybe it's because the picture is in a table (with the image as the background of the table, defined in CSS). I'm using driver version 4.11.2560. I will post screenshots and more info later.

Sorry, I forgot: my OS is win98 SR-1 (the service-pack made no difference), and the graphics card is of course AGP. GIF and PNG makes no difference.

I checked with Dan Matejka (sp), who has a Rage LP Pro AGP 2X card, and can't reproduce this problem.
Comment 16•25 years ago

The card in question is available for $25 from eBay. If this is still occuring and can't be traced to an old driver or whatnot, I suggest we just buy one and try it out.

Folks who are encountering this bug: Could you please comment in this bug report with what driver version(s) are you using for your ATI video card? (if you haven't already) Thanks!

I've switched from my ATI Rage IIC to a 3D Rage Pro AGP 2X (aka Rage Pro Turbo). Still have the same problems with Mozilla (and interestingly enough, Communicator 4.7x) on Windows NT 4.0 SP6A. Was using an earlier version of the drivers. Upgraded to the latest on their web site, 5.2.04 and still have the problem.

Vernon (devrel@ati.com) has reproduced this problem in-house at ATI, and will be filing a report for their engineers regarding the issue.

Eli, Could you ask Vera to make a release note of this ATI card problem? Thanks, Neeti

Already done (of course!)

Hi, all --- Vernon at ATI recommends trying the 5.38.2B08 of the Rage Pro NT driver from < http://www.ati.com/na/pages/spdrivers/index.html>. Sorry for the very slow follow-up on my part (it's been a month). Would anyone be interested in checking whether the new driver helps, and if so, posting here? (I'm not sure whether they're rolling these patches into a mainstream driver or not.) Thanks!

I'm getting this problem in all colour depths (see bug 47287). I tried the beta ATI driver, but it doesn't work (won't init after reboot), probably because the ATI 3D Rage Pro in my PC has been mother-board integrated by Dell and you have to use Dell drivers. ATI would have to release a driver with this fix to Dell for the millions (?) of Dell-with-Rage-Pro users to get this fix. I did try the latest Dell-ATI driver, but it is still broken. I can't help thinking that there should be a way around this driver issue. No other apps on my PC, including IE, have problems rendering images. I know of many Dell + NT + Mozilla or Netscape 4.x users that have this problem.

I have had the same problem. My config. is K6-2 400Mhz Epox Mvp3-GM ATI Xpert@play98 (RagePro Turbo chip) Netscape 4.73 and Mozilla build 2000-11-01-04 The problem is known by ATI and they have fixed it for the Rage128 cards. (but not Rage Pro) However I don't think this is a ATI driver/hardware problem because it works in Internet Explorer. http://support.ati.com/infobase/3193.html Other problems with Netscape/Mozilla: 1. Animated gifs is rendered with a non predictable result. 2. Scrolling up and down will make white lines across the image. Both these problems are covered in ATIs Infobase - but I can't find it. I have however found a work around for the problem and that is to change the Front side bus from 100Mhz to 66Mhz(Memory speed). The only problem is a CONSIDERABLE performance loss. I think we need to fix this problem because the Rage Pro series is one of the most used graphics chips in the world.

The Epox MVP3-GM is a motherboard. The problem I can't find anything about in ATIs infobase is the "Animated gif" problem - I know it's in there, I just can't find it.
