Description
There are several problems with the implementation of Direct3D9Ex feature on Windows 7. 1) It has caused a serious performance regression: RT-27508 2) There are visual artifacts when coming back from a screen lock or sleep: RT-27121 (which has had several duplicate issues filed against it). 3) The native code that handles uploading the textures in 9Ex mode is unsafe in that it stores a pointer obtained from getPrimitiveArrayCritical that could (in some cases) possibly by accessed after the array is released. This is a crash waiting to happen.
