830697 - delay showing the widget until we've completed the layer transaction that renders all the contents of the widget

Status: NEW

(Core :: Graphics, defect)

Description

[Girish Sharma [:Optimizer]]

Read https://bugzilla.mozilla.org/show_bug.cgi?id=794246#c23 and the whole bug for complete reference.

A small reference : 

I can see the following behavior clearly while opening (book|feed)marks menupopup:

1 First the border is painted with the whole popup transparent.
2 Then the popup is painted with the bookmarks/feeds .

Although it is much faster than before bug 794246 landed, and it does not lag with time.
IMO, this painting should not be separately visible at all.

If the reason for step 1 and 2 being clearly separately viewable is the time taken to draw the menu items, then there can be a workaround, that when we draw the border of the box, draw the same colored background also. This will make the opening of popups snappier.

I think what we need to do there is to delay showing the widget until we've completed the layer transaction that renders all the contents of the widget. Please file a new bug for that?

It would be really nice if something other than delay is the solution

Should this bug be RESOLVED FIXED after landing bug 832641?

Its much much faster now. But this bug is still valid.
