597538 - when switching tabs, flash content on new tab paints before the new page content

Status: RESOLVED INVALID

(Core :: Layout, defect)

Description

[Mike Shaver (:shaver -- probably not reading bugmail closely)]

A is page content on the original tab; 'a' is flash content on original tab.
B is page content on the new tab.

I'm seeing


AAAA
AAaA
AAAA

(click on tab B)

BBBB
BBaB
BBBB

(after a tiny amount of time)

It makes the transition feel slower, and that flash is faster than we are.  Also kinda ugly.

It either has to appear a little early or a little late with the current setup. It should be arriving late on Windows though, so we should look into that.

Post-FF4 we can reduce the delay more when we reorganize things to make all painting happen through the refresh driver.

We're in the process of removing support for plugins (bug 1677160) and bug 1687239 has removed the relevant Layout code, so this bug is irrelevant now.
