Description Niklas Dougherty 2002-11-19 03:19:58 PST
User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en-US; rv:1.2b) Gecko/20021031
Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en-US; rv:1.2b) Gecko/20021031

Consider an element border of immense proportions, say > 500px.

Situation 1: a <p>test</p> with a border of 1000px will make the text within the
paragraph disappear.

Situation 2: the same paragraph with a border of 30000px will be completely
shattered into checkered patterns and weird diagonal cuts.


Reproducible: Always

Steps to Reproduce:
1. Load testcase 1
2. Load testcase 2
3. Ponder the style algorithms

1000px border

Use Find to find the text, since it is black on black due to the border eating
inwards.

Scroll around and see the Cubism.

This is not the usual "forgot to paint this area" that is covered in another
bug. This is a consistent _diagonal_ cut that doesn't go away by going back and
forth.

This works fine for me on Linux.  Is it Mac-only or it it just that the amounts
required to trigger the bug are different on different platforms?  ->GFX

I do see strange things happening on linux.

I see it now.  Not sure why I didn't earlier.  Perhaps related to bug 115526,
although it's not fixed in my tree.  However, it may not be.

Comment 8 Zack Weinberg (:zwol) 2011-11-15 18:16:02 PST
I do not see the "cubism" on Linux but I do see the text getting covered up by the border in both test cases.  Recategorizing.
