From Bugzilla Helper:

If a rectangular image has it's width set using CSS proportinal units in a style
sheet, e.g "width : 8em;" or width : 20%;" it is not redrawn correctly when it
is partially obscurred by a context menu for example. 

The demonstration URL demonstrates this problem and includes an image which is
"square" that does not demonstrate this problem.

Reproducible: Always
Steps to Reproduce:
1.Author a page including a rectangular image
2.Set the image width in a CSS stylesheet using a CSS proportinal unit
3.When displaying the page create a context menu that partially obscures the
image, the menu needs to be positioned to the right of the left hand side of the
image.

Actual Results:  The images displayed were corrupted. The corruption displayed
was dependant upon where the context menu appears, in some cases parts of the
image are not displayed, in other cases part of the image is redisplayed offset
inside the original.

Expected Results:  Displayed the complete image without any corruption
