43685 - Fonts change randomly, displays in mixed sets of fonts.

Status: VERIFIED DUPLICATE of bug 43490

(Core :: Layout, defect, P3)

Description

[laurel]

Using jun23 m17 commercial build
Noticed on linux rh6.0 and NT 4.0
Have not seen on Mac OS 9.0

Throughout the product, but seen drastically in the mail window, display fonts
are changing upon apparently random actions such as providing login password,
changing folders, clicking toolbars -- no apparent pattern.

When the fonts change, all display fonts in a given area, window or pane do not
all change at the same time, resulting in a display of mixed fonts. For instance
folder names will display in one font and newsgroups will display in another
font type.

Areas which have been seen to be affected:
Mail:
   -- toolbar buttons
   -- folder pane
   -- thread pane
   -- message pane
   -- header envelopes (upon clicking the expand recipients widget)
Other:
   -- profile manager
   -- browser toolbar
   -- browser status bar
   
I don't know who this would ultimately belong to. It's been noticed for a couple
builds.  I looked to see if something had been logged in the browser/elsewhere
and nothing jumped out at me.

see bug 43409 - could be the reason.
I got odd font-changes in menus before altering back to screen_resolution 96
(instead of 9696).

cc'ing hyatt. I'm going to reassign to ben though I'm not sure if he's the right 
person, I just don't know who is.  It looks like some strange things are 
happening to skin related areas. At random moments, fonts and background colors 
change on me.  I don't know if this is layout or skin related.  Any help would 
be appreciated.  It's been doing this for the last few days.

There is no apparent harm caused by this bug, but it's highly visible, and it's 
on all platforms.  I'm going to nominate nsbeta2 so PDT can make the call.

Here are examples of what the user may see:  
1)  sort on a column in the thread pane and the fonts of the messages listed in 
the thread pane change from a non-serif font to a serif font.  The rest of the 
application remains in a non-serif font.  
2)  expand on the recipient list in the message header area.  The font will 
change on in that area

Putting on [nsbeta2+] radar for beta2 fix.

Changing product to browser ...

Ben, says this has nothing to do with skins or skinability.  Must be some layout
problem.  Over to the module owner ...

Re-assigning to myself for a more detailed triage...

I can't see this any more with today morning's debug NT commercial build either.  
Marking qawanted and updating status whiteboard.

Could this be because Marc Attinasi turned off style context sharing?

Comment 10

[Nisheeth Ranjan]

I checked with Marc on this and, yes, David is right that this bug is now fixed 
because style context sharing is turned off.

Marking this as a dup of bug 43490, the bug that Marc fixed when he turned off 
style context sharing.
