This is split from bug 500200 to track the corruption caused by interleaving hardware and software rendering.

Attachment: A standalone executable showing the problem

This program shows the same corruption as we're seeing on the new tab button.

All it does is draw from a directdraw surface, an image surface, and then a directdraw surface in quick succession. 

If we spin before drawing the top surface the corruption goes away, so it does indeed look like a cache problem of some sort.

Attachment: An example Makefile

This is an example Makefile that I used to compile the program attached. It will probably need some adjustment to work for other people.

This hurts a lot, but it should block. Sadly, we're blocking on NVIDIA fixing it.

Will investigate and traige at NVIDIA.

WinCE/Windows Mobile support has been removed from the main build system, Spidermonkey, mobile installer, in-app updater and so on (see bug 614720, bug 554087 and all their dependants). Until such point where MS decide to release a Windows Phone 7 NDK and the decision is made to port to that platform, this is WONTFIX.
