Terminal shows repeated gdk_pixbuf errors at hw tune on kali

[jonshorter]

Describe the bug
On a clean install of Kali under VMware (VMWare tools installed), and using the latest iceman fork, running hw tune brings up the graph but terminal is full of errors, especially when changing the size of the Overlays window.

To Reproduce
Steps to reproduce the behavior:

1. set up the environment as described
2. start pm3
3. hw tune

Expected behavior
A clear view of the output from hw tune

Additional context

Appears to be the same issue as documented here (wrong theme)...
https://ubuntuforums.org/showthread.php?t=1639829

@jonshorter same was on Ubuntu -see #354
It is a problem with the theme.
You could try to fix the theme or change it. In Kali I have the same pixbuf warning.
Or you change the theme (Applications: Adwaita, Blackbird,...) as a workaround.

[iceman1001]

Sounds like Theme has issues on both Ubuntu and Kali.
Maybe open an issue at their bugtrackers?

Some fast googling, and stackover has some ideas.

As simple as that! Man I feel foolish heh .. switched from Kali-X to Kali-X Dark theme and all is good! Sorry about that .. I was googling way too deep into things.
