Any image from http://alt.ngs.noaa.gov/katrina/KATRINA0000.HTM breaks Firefox. 
The initial scaled image display works.  Zooming the image paints the first row
of pixels all the way down the screen.  Then shrinking the image again displays
bit trash all over the image canvas.

Reproducible: Always

Steps to Reproduce:
1. Load the image in the URL
2. Click on the image to resize
3. Image displays incorrectly (IE does it right)
4. Click on the image again to shrink
5. Image contains trash.

Actual Results:  
Image is corrupted

Expected Results:  
Image should display in both large and shrunken formats

Can any of you confirm this in 1.0.6?

Comment 5

This WFM in 1.0.6. Please reopen if you can reproduce with a clean profile in
the latest builds.

I see this in the latest branch nightly on Windows XP as well.

Reproducing is easy for me. Simply open the image and wait for it to finish
loading and you'll notice small amounts of corruption at the bottom of it (image
to be attached). If you zoom in, you'll notice you're not actually zoomed in and
will see that it's just random colors in straight lines... yay. Finally if you
zoom back out, it gets completely corrupted (image to be attached).

For what it's worth, it eventually showed fine and I had to restart FF to get
the problem to re-occur, but switching tabs after it's been fully loaded
normally causes it to happen more often.

Attachment: Minor corruption on first load

Attachment: Major corruption

This occurs either after zooming in and back out or after switching tabs after
the image has been fully loaded.

Reproducable ~8/10 times.

Showing corruption on zoom (using latest-trunk)

[Thomas Swan]

I can always reproduce in Firefox 1.0.6 and trunk, but I cannot reproduce in
Mozilla 1.7.11.  It seems Firefox specific.

Comment 11

[Thomas Swan]

Some corruption seems to happen on repaint operations as well.  Switching from
tabs as noted above gives different trash patterns, full-zize and shrunk.
