614111 - Direct3D 9 (non-ex) Devices cannot be reset

Status: RESOLVED FIXED

(Core :: Graphics, defect)

Attachment: Clear and recreate VertexBuffer on device reset

For a while now we've had D3D9 devices use a VertexBuffer in D3DPOOL_DEFAULT. This is fine but it means the buffer needs to be released and recreated when a device reset is performed on a non D3D9-ex device (for example after screenlock), otherwise the device reset will fail and we will consider the device lost beyond hope and recreate all layer managers.

This is a big problem for Windows XP.

Add missing return true.

sounds like we need to change this from nominated for 2.0 to blocking beta8 to reduce the volume of the #1 top crash on trunk (bug 611597).

Can we just used D3DPOOL_MANAGED to avoid loosing the vertex buffer on device reset?
