Status: RESOLVED FIXED

(Core :: Layout, defect)

Description

[Jesse Ruderman]

Attachment: testcase (should have a white background)

The page background should be light green.  For the left half of the page (which is very wide), it is black instead.

catlee noticed this while looking at a *log file* from my dom fuzzer!

Not just on Mac apparently.

I've seen this on and off, it's not very good. I'm going to request blocking for this one.

Same regression range & similar symptoms to 586627 -- maybe a dupe?

Comment 6

[Daniel Holbert [:dholbert]]

er, I meant "bug 586627" (I forgot the "bug" for automagic linkification)

Comment 7

[Joe Drew (not getting mail)]

Alice suggests this is caused by retained layers in comment 1.

Comment 8

[Daniel Holbert [:dholbert]]

If this is a dupe as suggested in comment 6, then it may be fixed by the patch posted on bug 582146.

Attachment: another trigger

Another trigger.  Not sure if this has a word with over a million chars or not.
