Yes, Indeed I too face this issue.
Goto pcd_viewer.cpp (in pcl/tools)
Add the below line, before (p->addText3Dpcl::PointXYZ (ss.str (), pos, 0.0005, 1.0, 1.0, 1.0, ss.str ()))
p->addSphere<pcl::PointXYZ> (pos, 0.0005, 1.0, 1.0, 1.0, ss.str ());

Build the viewer you can able to see this issue. Adding my pcd file.
