Tested and reproduced on Unity 4.3.3f1, 4.3.4f1, 4.5.0b5, 5.0.0a2;

Editor hangs when launching it with DirectX 9 on PC or tablet which has Intel HD 4000 graphics. Editor stops hanging resuming PC or tablet from "sleep" or "hibernate" modes. (Attaching screenshot picture "hanging.png"). Also attaching log file "434Editor.log".

Log file always shows this error:
(Filename: C:/BuildAgent/work/d3d49558e4d408f4/Runtime/GfxDevice/d3d/D3D9VBO.cpp Line: 632)
FAILED(hr)

This behavior happens when creating a new project and selecting any random package to import (i.e. "Character controller.unityPackage").

Sometimes editor loads successfully, but the whole text becomes to look like squares. (Attaching screenshot picture "squares.png").
Also attaching log file "500a2Editor.log".

Repro steps for Windows:
1. Open Windows command promt (Win + R. Write "cmd" and press enter)
2. Locate Unity install location.
Use commands:
a) cd "c:\Program Files (x86)\UNITY-version\Editor"
b) Unity.exe -force-d3d9
3. Editor will start. In start screen press "New Project". Select "Character Controller" asset to import to your new project.
4. Unity loads with artifacts or hangs.
