repro:
open FF
open url
press on the link "this reference rendering"
when I press [back] and [forward] the reference is rendered properly

result:
see screenshot

expected:
the correct image

I'm not sure what the cause is, I can't repro with restarting FF

Component GFX:Thebes ?

I'm not sure when this regressed

Could not reproduce in 3.1b2pre under Linux or Windows. Reference rendering showed just fine for me.

The same grey image with
Mozilla/5.0 (Windows; U; Windows NT 6.0; sk; rv:1.9.1b2pre) Gecko/20081017 Minefield/3.1b2pre nightly
when loading acid3 reference for first time. I can't reproduce it after restart.

Caused by a plugin maybe? Try disabling them.

Tested with a fresh new profile, of course. And I can reproduce it with another new profile.

So, it doesn't seem to render the background-image(reference.png), just the background-color (#c0c0c0)

in reference.html this is the line

<style type="text/css">
body { background: #c0c0c0 url(reference.png) top left no-repeat; margin: 0; padding: 0; }
</style>

Plugins are often installed for all users; a new profile does not guarantee you're starting without plugins, just extensions and themes.

Works fine here, with my default profile and with a new profile

It seems a sort of lack of refresh.

After opening "View Page Source" window and moving it on top of the grey rendered reference page, the part that were hidden by the window started getting the proper colours.

I closed the source window that acted as a sort of "correct rendering paintbrush" (also the "right mouse button menu" acts as refresh paintbrush),
switched to another tab and then back to the page, and the grey part was completely disappeared.

Did you check your plugins? Only certain people seem to be able to get this and plugins would be the most likely thing to differ between people. (plugins aren't even disabled in safe mode or a new profile)

Comment 12

[Peter van der Woude [:Peter6]]

This bug has nothing to do with plugins

To reproduce it I have to empty the cache before clicking on the reference rendering link.

Latest working (that is, if I clean the cache and click the reference rendering sometimes I can still see the grey version for less than a second, but then the correct one appears):

Build identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1b2pre) Gecko/20081011 Minefield/3.1b2pre

first with the regression:

I'm guessing this is the same as bug 460796.

Duping forward because the other bug is simpler and clearer.
