I cannot seem to reproduce this bug, what's your distro?

[Xoslorg]

Archlinux with gnome.

[korcankaraokcu]

I've done a clean installation of archlinux gnome and can confirm that this issue exists for the specified distro

I've fixed this issue by running export QT_QPA_PLATFORMTHEME=qt5ct on my end. Can you try running this before running pince and tell me if it works? I think you also need to install qt5ct before doing so

[Xoslorg]

Thanks, the problem is solved perfectly on my laptop, at home I will try with the desktop.

[korcankaraokcu]

Thanks for confirming, apparently this is a gnome related issue. There's a PR that upgrades the pyqt version to 6, if that doesn't fix the issue I'll try to include this in the installation script. Have a nice day

[korcankaraokcu]

Apparently this issue doesn't exist in pyqt6, that's a relief

[Xoslorg]

With last updates get same error.

I've done another clean installation of archlinux gnome and unfortunately cannot reproduce the bug above, it's gone after pyqt6 upgrade for me. Maybe try the solution above with qt6ct?

[Xoslorg]

With clean installation

with clean installation and qt6ct

#116

Apparently Offpics has been able to fix it by installing qt5ct and launching it, maybe try that with qt6ct? You probably already installed it, telling that just in case if you haven't launched yet

[Xoslorg]

same result with qt5ct
/opt/PINCE/GUI/SettingsDialog.py:314: Warning: g_object_get_is_valid_property: object class 'GtkSettings' has no property named 'gtk-fallback-icon-theme'

[korcankaraokcu]

No I meant qt6ct and launching it

[Xoslorg]

Yes, first with qt6ct.

[korcankaraokcu]

Try inserting this to the beginning of pince.py

import gi

gi.require_version('Gtk', '3.0')

This apparently worked for someone else, hopefully it works for you too

[Xoslorg]

Good, I just tried it and now it works, thank you very much.

[korcankaraokcu]

This will be most likely added to pince soon, I'll notify you

[korcankaraokcu]

The patch is up, you can revert your local changes and update the project with git pull
