How to get rid of Long Dialogue window

Hi, Thank you - it fixes it in the normal ParaView (without additional theme).
However, once I run it with dark-theme, It goes back to same error again. And it remains even if I run without theme. Using dark theme also hides the clickable buttons, see example below:


This (buttons not visible) happens even with ParaView 5.11.1. But with ParaView 5.11.1, using theme does not make windows wider. Could it be due to some compatibility issue with my OS? I am using RedHat 9 where I am facing this problem.

p.s:

When running ParaView with dark-theme paraview -style=default -stylesheet=/absolute/path/to/style.qss, it also gives a warning saying

QApplication: invalid style override 'default' passed, ignoring it.
	Available styles: Windows, Fusion

in version6.2.0, and the following in version 5.11.1:

QApplication: invalid style override 'default' passed, ignoring it.
	Available styles: HighContrastInverse, HighContrast, Adwaita-HighContrastInverse, Adwaita-HighContrast, Adwaita-Dark, Adwaita, Windows, Fusion
