The server is not accessible.  Can you attach the testcase here?  Use the 'Create a New Attachment' link.

Attachment: A zip file of the html and css files.

Hope this is useful.  I din't know how else to provide it.

Attachment: "minimal" testcase

This testcase is based on the original URL provided by the reporter.

Basically, all this contains is a large amount of text contained within <pre style="overflow:auto;">. Removing the "overflow:auto" resolves the problem.

For me, this not only does not render, but also when I try to scroll up and down, after a short while the scrillbar freezes, and the entire browser window becomes unusable (the view area does not refresh even when switching to other tabs).

This might be a duplicate of bug 111561 via bug 160483, although the symptoms are a bit different.

Also, I forgot to mention: I'm seeing this with:
Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.9a1) Gecko/20051018 Firefox/1.6a1
(as well as recent 1.8 branch builds).

Hmmm - when loading my testcase from bugzilla, the content does initially appear to render, but resizing the window or scrolling down causes it to vanish.

Also, I currently can't reproduce bug 111561 / bug 160483, so either the URL they're pointing to changed (neither has an attached testcase), or this is not really a duplicate.

I'm moving this to Core/Layout, and CCing bz (which will probably tell us this is a dupe ;-)

Yeah, this is a dup about widgets not being able to be bigger that 16bits coordinate-wise (so at most 32000 twips tall).

"Minimal" testcase confirmed on 2 builds:
Mozilla/5.0 (Windows; U; Windows NT 5.0; ru-RU; rv:1.7.2) Gecko/20040808
Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.8) Gecko/20051111 Firefox/1.5

If style overflow:auto or overflow:scroll applied to any block container (not only to pre) without height limitation, but with large amount of text, scroll down after some moment causes fail of rendering this text. E.g., 700kb text fails to render on ~20%. Scroll up resumes rendering.

Read my comment above.

We read it the first time.

I've got a similar problem. See the attached testcase.
After opening the page and scrolling down (with keyboard, mouse wheel or scrollbar), suddenly the page gets completely black.
Removing the overflow:auto or the margin:0 fixes the problem.

Is this the same bug I'm hitting?
