Case share of hardware transform-error failing back to software

[sum2012]

Lenovo IdeaPad Y470
Integrated GPU model:HD Graphics 3000
Discrete GPU model Nvidia GeForce 550M
OS:Windows 7 64 bit
My friend said that when play game,it will show " hardware transform-error failing back to software"
When he update graphic driver,the problem solved.
Attach problem log

Code:

42:44:060 user_main    E[G3D]: GLES\ShaderManager.cpp:64 Info log: 0(3) : error C7538: OpenGL does not allow 'lowp' after 'inout'
0(5) : error C7538: OpenGL does not allow 'lowp' after 'inout'

Hm, we currently generate like this in the vshader:

Code:

in lowp vec4 v_color0;

Maybe we should instead output

Code:

lowp in vec4 v_color0;

for compatibility with these drivers. I think I need to check the GLSL specs...

My notebook can also reproduce.
Can you give me the code to test ? Thanks
