Hi, Thank you - it fixes it in the normal ParaView (without additional theme).  
However, once I run it with [dark-theme](https://discourse.paraview.org/t/how-to-get-paraview-dark-ui-any-os-any-release/4545), 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:

 ![paraview_theme_error](https://discourse.paraview.org/uploads/default/original/3X/4/d/4dcbd032024528d06c4925d5af180b22b25b2b6e.png)  
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

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

```

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

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

```
