79552 - Toolbar images flicker, if moused over

Status: VERIFIED DUPLICATE of bug 75474

(SeaMonkey :: MailNews: Message Display, defect)

Description

[Håkan Waara]

This has been for a long time now, so no special build (maybe a modern3 or
later) is required.  Reproduce it like this:

1. Open up mailnews
2. Drag the cursor, as fast as you can over all the toolbarbuttons (without
holding the mousebutton down).
3. Do this repeatedly - they flicker as they switch state from "normal-image" to
"mouseover-image". Like if they were reloading all the time and not buffered.

I have no idea where this belongs (themes, libpr0n, mailnews, cache, xptoolkit?)
so I'm CC'ing one representant of each module and will let you sort out who the
assignee for this bug should be.  Sorry for any inconvenience.

What build was this from?  I just checked in some modifications to the cache on 
Monday afternoon that should keep chrome images in the cache longer.

This is in 20010508. I will comment here if it's not still there in the next
build I download.

They still flicker in 0509, like if they were repainted each time they got a
mouseover or something...

Turns out that this is a global problem, hence why I reassign to the imglib 
guru saari. It's not mailnews specific.

Andreww, kerz said that you fixed something similar to this lately.

This problem is ugly and it is flickering every time you mouse over/out of the 
image, so it looks like it's reloaded every time or something. A good testcase 
is the Editor toolbar.

Hrm, sounds like we still have chrome caching issues. Target 0.9.2
