Blank Map at startup And No label in debug build

[hoss291069]

Hi
I compiled Tangram-es in Windows with MSVC in QCreator IDE.
When I run default example (Tangram.exe) it's show only blanck window with background color I defined in scene file. But when I change zoom by mouse wheel map appear and some time's when changing zoom it again disappear.

Another problem that I have is that in debug compile labels are not rendered.

I run code with gpu debug config like below:
glEnable(GL_DEBUG_OUTPUT);
glDebugMessageCallback( GLDebugMessageCallback, NULL );
glDebugMessageControl(GL_DONT_CARE, GL_DONT_CARE, GL_DONT_CARE, 0, NULL, GL_TRUE);

and the output was below line repeated several times.
131204: OTHER of LOW severity, raised from API: Texture state usage warning: The texture object (0) bound to texture image unit 0 does not have a defined base level and cannot be used for texture mapping.
