Workspaces background unexpectedly turns white

[jajo-11]

The background of Workspaces turns white but only if i have only chromium in that workspace.

Here is the workspaces part of my style.css

#workspaces
{
    background: transparent;
    margin-top: 1px;
    margin-left: 2px;
    padding-bottom: 1px;
}
#workspaces button
{
    color: darkgray;
}
 #workspaces button.focused
{
    color: white;
}
 #workspaces button:hover {
    box-shadow: inherit;
    text-shadow: inherit;
    color: #58abb7;
    background: transparent;
}
 #workspaces button.urgent {
    background-color: #f77923;
}

As evident in the style.css the background should be transparent like the rest of the bar.

Are your background white?

[jajo-11]

No. All my backgrounds are set to "transparent". This is how the Workspaces area looks like when chromium is not open:

Ahh i see, you must have the following block.

window#waybar.chromium {
    background-color: #000000;
    border: none;
}

Or something like that, no?

No here is my full config:

By the way i am running:

• Waybar v0.8.0
• Chromium 77.0.3865.90 Arch Linux
• sway version 1.2 (Aug 29 2019, Arch Linux)

Are you using a theme?

[jajo-11]

What kind of theme?

[Alexays]

GTK system wide theme

[jajo-11]

I do, it is called Qogir, but i observe the same effect on other themes as "Clearlooks", "Crux" and "Raleigh"

My waybar turns black, and I have wlr/taskbar enabled whose icons gain a huge white border, when Chromium is open. It doesn't happen with any other app on my system. Should I open a new issue for this?

EDIT: Looked at style.css and disabling the .chromium bit as mentioned above fixes the color problem, however, wlr/taskbar's icons still gain a white border on the workspace Chromium is in.

EDIT2: Okay styling taskbar button like so fixed it for me:

#taskbar button {
    border: 0px;
}

Just required a little rubberducking, heh.
