No flicker issues with D2D off -

Flash window is flickering even without D2D for me, but only when scrolling in this case.
But with D2D, flickering is much easier to see.

Expected ?  How so... Expected is smooth playback of videos not corruption and flicker and odd things when trying to mouse around and find the controls for the video whe d2d is enabled. 

So, is this a d2d issue or something being brought to light when it is enabled? 
Title should be changed to show [D2D]- Flicker on embedded videos

Well, the changeset that caused the regression doesn't affect windowless plugin drawing - therefor it's expected that the regression only affects windowed plugins.

That's the question, from what Loic says it appears to be an issue anyway, brought to light by D2D, but I can't be sure until I've investigated more.
I don't think D2D is the root cause. The same type of flickering occurs when scrolling the page without D2D. You're probably seeing flickering on D2D without scrolling because this new bug is interacting with a previous unfixed D2D bug. Flickering (same type without D2D) does occur though under D2D while scrolling.
Hardware: x86 → All
This bug does not depend on D2D or even Windows Vista/7.  It is fully reproducible on Windows XP, which doesn't support all that.
This bug seems to be applicable only with the youtube player.

No problem with customized flash players on :
vimeo.com
dailymotion.com
cnn.com
Also affects hulu.com

Also
top page of www.yahoo.co.jp
Popular free movie site  gyao.yahoo.co.jp

Forgot to mention that my toolbar will flicker on occasion as well as the contents of a sidebar.
Also happens on Windows XP without D2D
especially visible on this page, lot of flash apps long page http://www.zdf.de/
Affecting many flash components to the point of being unusable.  Scrolling or moving mouse would give epileptics seizures.

Win7 Ultimate x64, NV 9800GT, D2D NOT enabled

Not that I'm complaining, but is it just me or has the past week of FF4 nightlies seemed VERY unstable with many regressions or bug introductions?

Hrm, that might be somewhat expected for D2D Enabled, simply since it's very hard to test across the diversity of hardware we see in the wild, but it's definitely not expected for D2D disabled ofcourse.

Are you sure it's disabled? (i.e. check about:support)

My bad, D2D is enabled.  I was looking at an about:config value which apparently no longer applies.

Yes, -1 selects the 'default' render-mode, which for people windows Vista or 7 with DirectX 10 hardware is Direct2D.
Blocking on this regression. Bas, this sounds like something you should work on, if not, please reassign appropriately.

Seems to be fixed. (on YouTube is ok) .
But checkout here: http://www.blic.rs/ scroll down on right side look for Canina flash ad. Try scrolling and you will see issue with that flash.
@ Oskar
Nope it seems fixed no issues also with this canina ad you talking about
I think that Canina flash ad issue is related to https://bugzilla.mozilla.org/show_bug.cgi?id=587508.
