Hi,
this is graphic related problem. You can add following option at the end of config.pro file
graphics win32_gdi
The option turns off OPENGLgraphics, therefore ProE window will be blinking during rotation.
Note: You are using old software in combination with new operating system. You can't expect that old software will behave nicely all the time. It is developed for Windows XP not for Windows 10.
