Paraview window had no menu.
I installed paraview 5.3 x64 on a fresh windows 10 build 15063.0, and paraview window has no menu! Also, everything is moved up about 60px, I mean you have to click about 60px below an icon (or anything else) in order to click it. screenshot
Also a warning is shown in output window:
paraview QWindowsWindow::setGeometry: Unable to set geometry 3840x2004+4+60 on QWidgetWindow/'pqClientMainWindowWindow'. Resulting geometry: 3836x2004+4+60 (frame: 4, 60, 4, 4, custom margin: 0, 0, 0, 0, minimum size: 955x1001, maximum size: 16777215x16777215). (:0, )
Note that my screen is 4k (3840x2160) and 240 dpi.
