Hallo everybody and thanks for your help.
I'm trying to install an app I need to use for remotely signing documents (app's called ArubaSign) but unfortunately I can't use it because main windows remains white, without options. I'm using dozens of apps without problems, but this one is a real pain! I use KDE Plasma 5.27.9 - KDE Frameworks 5.107.0 - Qt version 5.15.10 - Kernel version 6.5.0-5 amd64 - Graphic platform X11.
I attach journalctl, in case you need it
Thanks alot
