I can no longer use the color picker from the gcolor3 app. Could you please test
if this is also broken on your Xfce?
1. Run: sudo dnf install gcolor3
2. Run: gcolor3
3. Click the color picker
4. At this point it should let you pick a color from the screen,
but does not for me
I have Fedora 33 with Xfce 4.16 from Copr:
I want to check if this has stopped working in Xfce 4.16.
Thanks for help.
