Cmake-gui seems corrupted. Shows incomplete dialog box without any buttons

Recently i updated to the new version 3.16.3 and since then i dont see the complete dialog box. I even reverted to little older version(3.15.5) there too, i see the same problem.

Please refer the snapshot attached for the cmake-gui

I am unable to select or change the flags from the CMake cache. Please help me to resolve this issue. If you need more details, let me know.


Infact there was no issue actually.

Move the mouse cursor to the top of text widget and you will observe change in mouse pointer to interface arrow.
Click, once the interface arrow is seen and the button view would be seen
