Should be the same with Nextcloud applied theme

SnappyMail 2.20 uses var() settings in CSS of your theme.
So your theme might have issues.

Try Nextcloud default or Breeze Dark.

Also report which Nextcloud theme you are using.

@the-djmaze as you might see in the pic am using Nextcloud theme on snappy mail and the Light theme on Nextcloud.

[the-djmaze]

Right. Where do you set the default to Dark?
Because i can't find that option in my Nextcloud

[the-djmaze]

Did you try the embed mode?

Ah, you are using Nextcloud 25.
Because everything works fine in Nextcloud 24.

So i went and installed Nextcloud 25 and i noticed that the theme of NC25 is horrible.

You should report to Nextcloud that there is something wrong with the :root variables.

Because SnappyMail just maps its own variables to that of Nextcloud. Like:

:root {
	--main-bg-color: var(--color-main-background)
}

But --color-main-background is black, not white in NC25

The issue is the way how NC25 controls theme colors

[data-theme-light] {
	--color-main-background: #fff;
}

Fixed in v2.20.1
