A problem with drawing points in OSG3.4.0

[XianranZ]

I'm experiencing something strange when drawing points with OSG 3.4.0. When I draw only one point, the program does not display the point. When I draw two points, the program displays two points, but the positions of them are wrong. When I draw three points, the program runs correctly and shows three points in the correct position.
Below are my codes and screenshots of the program running.

Draw one point code

The screenshot of program running

Draw two points code

Draw three points code

The difference between these three cases is only the number of points put in, the rest of the code has not changed. However they are not displaying as expected, why is this?
Looking forward to your answers, thanks.

This should help camera->setCullingMode(camera->getCullingMode() & ~osg::CullStack::SMALL_FEATURE_CULLING); /Tr.
