148446 - Missing lines in high-res images

Status: RESOLVED DUPLICATE of bug 115433

(Core :: Layout, defect, P2)

Description

[Dave Dyer]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; WinNT4.0; en-US; rv:1.0rc3) Gecko/20020523
BuildID:    1.0 rc3

a few (random?) horizontal lines of pixels are missing
from large size images displayed from the referenced
url.  This doesn't appear to be a problem for the
same release of mozilla for windows nt, ie; this seems to
be a mac (or max osx) only problem.

Reproducible: Always
Steps to Reproduce:
1. start at the referenced url
2. click on the first image to get a large version.
3. you should see a few obviously missing lines. 
4. verify that the lines ought to be there using a
different browser or os.

WorksForMe using FizzillaCFM/2002052305 (RC3).

qwext()(), please attach a screenshot of the problem.

qwext()(), can you reproduce the problem using a new Mozilla user profile?

Comment 4

[Dave Dyer]

behavior is unchanged when the launched application was
"mozilla profile manager"

Comment 5

[Dave Dyer]

also possibly worthy of note;  On my screen, the images display
in obviously line-at-a-time fashion.  Hitting "reload" after
the image has fully displayed seems to always result in a correct
image, but hitting prev-next to get back to the same image is likely
to produce another damaged image.  This appears to be a problem with 
on-the-fly scaling of the larger image.  

Also, I note that the pop-up window mozilla produces is too large
fot the screen - I cannot reach the lower-right corner to resize
the window.

(qwext()(), merely launching using the Profile Manager isn't enough. Did you
actually create a *new* user profile?

Comment 7

[Dave Dyer]

creating a new profile has no effect. The bug is still there.

Comment 8

[Chris Petersen]

Confirming issue in the June 02 OS X build (2002-06-02-05 1.0.0). Attaching
reduced test case soon.

The problem occurs when the image referenced is being scaled down from 1200 x
800 to WIDTH='921' HEIGHT='614'.

Attachment: Reduced test case

Image is being scaled to WIDTH='921' HEIGHT='614'.

Your testcase works for me in trunk 20030102, OSX 10.2.3

This may have been related to bug 115433, which also works now.
