Color Picker Bug on Arch Linux (GNOME) and Ubuntu Latest LTS (GNOME)

Hello, I purchased Substance Painter 3D Steam Edition and installed it on Arch Linux (GNOME) and on the latest 64-bit version of Ubuntu LTS (GNOME). I am encountering an extremely annoying issue with the software’s color picker.

The bug manifests differently depending on the distribution :

For Arch Linux – GNOME  :

When I click directly on the color, the widget does not appear at all—the click seems to do nothing. When I use the eyedropper tool, the screen turns black until I select a color (which ends up being black since the screen is black). After that, the screen returns to normal. This makes the software practically unusable.

For Ubuntu LTS (latest 64-bit version) – GNOME :

When I click directly on the color, the widget appears correctly and works as expected. However, when I use the eyedropper tool, the same bug as on Arch occurs.

Note : When I refer to the color and the eyedropper, I mean the main color picker as well as all the settings used to modify a material (textures, etc.).

Additional note : On both Arch and Ubuntu, the background color picker in the settings works correctly, but the eyedropper does not and causes the same issue described above.

Kind regards,
