Window appears, but can't select any GPU about radeon-profile HOT 3 OPEN

To use it I have to run it as root, i made a change to the .desktop file to account for it and all is well

from radeon-profile.

For reasons I don't know, launching it as root from CLI, it shows errors:

>sudo radeon-profile
[sudo] contraseña para root: 
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, xcb.

However, if I launch it as root with the "kdesu" command (equivalent to launch an application with root privileges in Plasma), it works fine. Then, I noticed two things:

• No graphs
  
• Text using "monospace serif" like in "General" tab (seems "courier" font) is slightly less readable in my HiDPI screen. Could you increase its font size 1 or 2 points?

Thanks

Installed with dnf on Fedora and ran into the same issue. It looks like there are a lot of negative reviews on the software center as well... maybe should change the .desktop file that installs by default or else few are going to have any success.
