Status: RESOLVED FIXED

(Core :: Layout, defect)

Steps to reproduce:

4 divs arranged to a cube and grouped under a parent div, each containing an image tag. The parent div is rotating around its vertical axis.


Actual results:

The divs containing the images flicker. If the rotation is stopped, flickering stops, but depending on the current rotation angle it may happen, that one of the divs is not displayed at all. This lets me conclude, that there may be a kind of z-buffer problem. The problem does not occur, if background-images are used instead of image tags. 


Expected results:

No flickering should appear.

I can reproduce the flicker in Firefox18.0Beta.
However, I cannot reproduce in Aurora19.0a2 and Nightly20.0a1 anymore.

I guess that Bug 806256 fixed this.

I guess Bug 806256 won't be uplifted to Beta, no?

Please re-nominate if this was a regression in FF17.
