Icon and dropdown list in Kicad have black background and are not visible (mono Light)

[maxknopp]

Hello,

With Mono light theme there is an issue with KiCAD, where icon and dropdown list use a black background which make icone and drop down list item not visible

When I try to switch to dark mode i have same kind of issue:

Is there a way to know which css property should be changed?

Issues with Kicad seem to be common with custom gtk3 themes. ( catppuccin/gtk#75, vinceliuice/Colloid-gtk-theme#102 ) .
I'll try to look into it but since it seems to be an application specific issue, the best workaround for now is probably just disabling mono-gtk theme for Kicad by setting GTK_THEME=Adwaita as an environmental variable when running it.
