调用mdVRLibrary.switchProjectionMode()多次切换模式会出现崩溃问题

调用mdVRLibrary.switchProjectionMode()切换如下两种模式相互多次后程序直接崩溃，代码如下:
if(isVRMode){
    mdVRLibrary.switchProjectionMode(getContext(), MDVRLibrary.PROJECTION_MODE_SPHERE);
}else{
    mdVRLibrary.switchProjectionMode(getContext(), MDVRLibrary.PROJECTION_MODE_PLANE_FIT);
}
