In the demo mentioned below we get a container layer with a visible region larger than its parent. This causes a problem in the D3D10 layer manager where CopySubresourceRegion tries to copy invalid data. This patch fixes that.

Given that this blocks one of our long-going top-5 crashers and might fix a substantial portion of that, I'd like to track it somewhere - if only to get things actually moving here.
Oh, and from what I remember, this crash signature also significantly regressed in 25, even though it has been quite high even before.
I believe Joe has landed this patch yesterday.
I tried to, but Inbound was closed. :(

Ah, yes, same here last 4 times I tried to land it. I'll try again tomorrow.

Is this safe for uplift to older branches as well? 23 is too far gone, but if it helps I'd love to have this for 24.

I strongly believe it is, but having it sit on nightly for 1 or 2 days might still be a good idea to make sure I didn't overlook some side-effect.
We could look at an uplift nomination if this is low risk enough, ideally before FF24 gets to Beta.
As Scoobidiver says in bug 805406 that this patch seems to fix 2/3 of the crashes with this PushClipsToDT signature, I think we should try to get this uplifted to 24.
needsinfo on Bas to help with uplift here.

If this is making the crash numbers go down -and- it seems stable on nightly so far, we should definitely uplift this!
