From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Win98; en-US; rv:0.9.4+) Gecko/20010925
BuildID:    2001092503

When I scroll the about:config list of preferences, the browser crashes when:
Scrolling down past font.name.cursive.x-baltic (index 162 on my machine) 
OR
Scrolling up past font.name.serif.zh-TW1 (index 230 on my machine)

The crash only occurrs when something attempts to be displayed.
I can scroll quickly past that range, and the crash doesn't happen.


Reproducible: Always
Steps to Reproduce:
1) type about:config in the url bar
2) scroll down (I did it with the mouse)
3) try to display some preference directly below font.name.cursive.x-baltic


Actual Results:  crash

Expected Results:  show the preferences without crashing


No talkback data, because talkback doesn't seem to catch the crash.

Here's two cut and pastes from the crash dialog:

could this be related to bug 101510, or is it completely different? methinks the
latter...

	Comment 2 • 23 years ago

btw, how are you scrolling? by dragging the scrollbar widget [holding down mouse
button and dragging], by using the arrow keys, by using the spacebar/pgDn/pgUp?

	djk Reporter
	Comment 3 • 23 years ago

Using build 2001092803 with Modern, I cannot reproduce bug 101510, yet can still
reproduce this one.
Too bad they weren't the same bug.

Mozilla crashes if I scroll any way:
1) grab scrollbar thumb/drag
2) click scrollbar arrows
2) click scrollbar region for pgup/pgdn
4) keyboard pgup/pgdn
5) keyboard arrows

I created a new profile (uses Classic).  It crashs also.

Reporter: Please try a talkback-enabled build:
http://ftp.mozilla.org/pub/mozilla/nightly/latest/mozilla-win32-talkback.zip

Then, if you get a crash, please post the Talkback ID here.

Alex:  I'm using the build /pub/mozilla/nightly/2001-09-30-11-trunk

I reproduce the crash, but talkback does not appear.  If there's something I can
do to force it to appear, please let me know.

I managed to figure out how to use Dr. Watson.

I'll attach the (text) log of the crash; hope it helps.

	Comment 9 • 23 years ago

djk: As the error cited is "gdi.exe", my hunch is that your crash is video-card
related, as opposed to Mozilla related (especially since Talkback isn't being
triggered).

Try upgrading to the very latest version of your video card driver.

If that doesn't help, try going to Display Properties ->
Settings -> Advanced -> Troubleshooting. Then, turn down "Hardware acceleration"
a notch or two. (You may need to reboot after changing that setting, I'm not sure)

	Mike Schuette
	Comment 10 • 23 years ago

djk: Running with the previous comment's hunch, could you let us know what video
card and version of the driver you're using??  Perhaps someone out there with
your configuration can reproduce this.

	djk Reporter
	Comment 11 • 23 years ago

I'm using an ATI RageII+ (Mach64) with 2MB RAM.

Driver version is 4.02, according to the display properties.

I am downloading new drivers from ATI right now.

This bug has been marked as a dependency of bug 104992, which is a tracking bug
for a possible ATI videocard issue.

	djk Reporter
	Comment 15 • 23 years ago

I changed the video card to a ATI Mach64 Rage Pro with default Win98 drivers,
and still got the crash.

I turned down the "Hardware acceleration" by 1 notch and can no longer reproduce
the crash.

Used an ATI box, crash. Swap VC's on a test boxt, then it's WFM. Marking new,
and saying that it has to be ATI related. Good job linking it to the meta bug,
saves me work finding it. :)

	djk Reporter
	Comment 18 • 23 years ago

I can re-reproduce it with build 2001103103. :-(

"Hardware acceleration" is in the same setting as when I said I couldn't repro
the crash (on 10/16).

I know that at least color-coding and sorting have been added to abouf:config
since then.

I'll keep testing and trying to find ways around this bug.

Unable to reproduce on Win2000 with CVS build(June 26'2002).

	djk Reporter
	Comment 21 • 22 years ago

I turned down my Windows "Hardware acceleration" to "butt-ugly-unsmooth
scrolling" (2nd notch from the left) and couldn't crash.

I'm positive there's an ATI driver issue, because that setting also cures a
rendering defect with scaled images in Mozilla.

	djk Reporter
	Comment 22 • 22 years ago

I upgraded my video driver with the file wme-j5-30-1-b02.exe from ATI's website.

I then turned the Windows "Hardware acceleration" back to the maximum, and still
got the crash.  The scrolling on normal pages was smooth again, however.

I kept the new driver, and turned the Windows "Hardware acceleration" back down
to the second notch from the left.

No crashes, and scrolling is still smooth!  Woohoo!

BTW, the following lines were added by Windows to the [display] section of my
system.ini file:
Mmio=0
SwCursor=1

djk, do you now get a Talkback window when crashing (Netscape Feedback Agent) ? 
If so, please post Talkback ID for this

though  i must add this bug was reported on Windows 98 and the 2 cases here that
are WFm are both NT based :)

	djk Reporter
	Comment 26 • 21 years ago

This bug blocks bug 104992, which is specifically about older ATI cards, and
mostly about Windows 98 (as the comments in that bug indicate).  I would think
that the newer Radeon series on newer Windows OS's would not have the same issues.

As my comment 22 indicates, I have found a WORKAROUND for this bug; now the only
problem is a 'stutter' when showing the same font.name* prefs that used to
crash.  FWIW, I think I remember seeing the same 'stutter' on another computer
with XP and a mobile Radeon, but no crash.

	Comment 27 • 20 years ago

Removing qawanted as it's pretty ATI driver is at fault here.
So if this is a driver bug, why is this bug report still open?

	Andrew Schultz
	Comment 28 • 20 years ago

actually, this is a dupe

*** This bug has been marked as a duplicate of 101055 ***

	Dave Warren
	Comment 29 • 20 years ago

How can this bug (OS=WIN98) possibly be a dupe of 101055 (OS=MAC)?

It appears to be driver related, so probably should be WONTFIX, but definitely
not DUPE.

	Andrew Schultz
	Comment 30 • 20 years ago

well, the release notes refer to bug 101055 (in the Windows section no less) and
some of the comments in that bug refer to problems with windows.
http://www.mozilla.org/releases/mozilla1.8b1/installation.html#win

Anyway, if it's not a dupe it's definitely INVALID.  anything but open.
