527334 - Image resize not working properly

Status: RESOLVED DUPLICATE of bug 526882

(Core :: General, defect)

User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:1.9.3a1pre) Gecko/20091107 Minefield/3.7a1pre
Build Identifier: 

I am displaying a large image (1920x1200) in a smaller browser window (1016x1439), so the image is resized to fit the browser.  If I click on the image with a magnifying glass, the image zooms to full size, but a column of it is rendered above where it should be.  Sometimes rectangular chunks of the image are missing.  Clicking on another window causes the problem to disappear. Scrolling the window so that it repaints the area of the image that has been affected causes the part occluded by the window scrolling to be fixed.  Moving the window itself does not fix the problem.  The problem generally does not occur again if the image is currently cached in memory.  However, if I switch to another image and then load the first one again, I get the problem again.

Reproducible: Sometimes

Steps to Reproduce:
1.  Load a larger image than will fit in the browser window
2.  Click on it to zoom to full size
3.  Portions of the image are missing or rendered in the wrong place.
Actual Results:  
Portions of the image are missing or rendered in the wrong place.

Expected Results:  
Image is rendered properly

You seem to have lots of opened tabs in the background, do you see the same if you test with only one tab?

This is a the same issue as bug 522708, which was duped to bug 526882.
