65605 - Images seem to become corrupted and/or take huge resources

Status: RESOLVED WORKSFORME

(Core :: Graphics: ImageLib, defect)

Description

[Justin Scott]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; WinNT4.0; en-US; 0.7) Gecko/20010109
BuildID:    2001010901

On multiple systems with multiple video cards, there seems to be an issue with
video resource usage. On a Win 98 SE machine with an ATI All In Wonder 128,
graphics will display fine but after a while of usage icons in the browser and
graphics on webpages become corrupted and eventually system must be rebooted as
Windows runs out of resources.  If left running, this problem will eventually
cause the entire system to freeze. (once the problem occurs, system must be
rebooted even if Mozilla is quit as the problem will remain)

On a WinNT Server 4.0 SP6a machine with a Permedia-2 based video card, images in
this build can become corrupted and display black squares and/or garbage.
Happens at any time (I.e., it doesn't take a while like the previous problem) In
the URL listed above, some icons before/after messages are shown as partially
black squares. It appears to be a transparency issue. (See URL
http://skipper.gseis.ucla.edu/staff/jscott/html/Images/mozilla.gif for an example)

Have only noticed these problems in Mozilla 0.7 after using the 11/16/00 nightly
build for months.  I am putting these bugs together as they appear to be related
(in how Mozilla is using system graphic resources)

Reproducible: Always
Steps to Reproduce:
1. Use Mozilla for an extended period of time (30-40 minutes of solid browsing)
2. Notice graphics becoming corrupted in Mozilla and other Windows programs
3.

Actual Results:  Graphics become unexpectedly corrupted		

Expected Results:  Graphics should stay the same as the beginning, or appear
correctly in the first place.

I should mention this appears to be very similar to bug #21981 (forgot to put
that in the original report, sorry!)

This works just fine for me I would bet its hardware dependant.

If it helps find differences, I have started running (nightly) build 2001011820
for Win32 and the problems seem to have become much less severe, if not
completely gone. (still get some weird image issues but nothing reproducable)
Will need a bit more time to test the Win98 machine but the NT machine mentioned
is much better. Possibly something in the Mozilla 0.7 branch that got changed?

Possible but so much stuff gets checked in everyday it would be hard to say
what. Please get back to us when you have some more information :) Thanks for
your time.

Marking WORKSFORME due to lack of response. Reopen if any more information to
the contrary becomes available.

Sorry for slow response, I've been following the nightlies a bit closer (am
using 2001020204 now) and the problem seems much better. Not 100% fixed but it's
much harder to make test cases that are consistent. Not reopening the bug over
it, though. May be more of a card driver issue now.
