Evolution dark background in HTML message (Jammy 22.04)

[Gavin Graham]

Impact
------
When using a dark theme in Jammy (22.04) beta, Evolution will display a dark background with black text for HTML emails in the message preview. Previously in Impish, the background was white with dark text.

This only occurs when using a dark theme, If you use a light theme, the background of the email is also light.

Release: Ubuntu Jammy Jellyfish (development branch)

Please see attached screenshot.

Test Case
---------
Install the evolution 3.44.1 update (not available yet)
Find a "plain" HTML email in your inbox.
Verify that the text is easily readable

One quick question.
On 21.10 the preview rendered with a white background even when using a dark theme.
Please see the attached.

And thanks for looking at this bug/question. I appreciate it. :)

Hi, i have the same problem, any workaround?

[Gavin Graham (gavingraham)]

This is not a bug rather a regression.

Thanks, it seems similar to https://gitlab.gnome.org/GNOME/evolution/-/issues/1835 which has been fixed in git and will be provided as a stable update when the next release is out

One workaround was also suggested

> try to set Edit->Preferences->Mail Preferences->HTML Messages->Unset colors provided in HTML mails in message preview

Please provide more details as I am unable to reproduce this bug with Ubuntu 22.04 LTS.

Could you run these commands in a terminal and let me know the output?

gsettings get org.gnome.desktop.interface gtk-theme

gsettings get org.gnome.desktop.interface color-scheme

[Gavin Graham (gavingraham)]

Hi,
Sure, the output is as follows:
gsettings get org.gnome.desktop.interface gtk-theme
'Yaru-blue-dark'
gsettings get org.gnome.desktop.interface color-scheme
'prefer-dark'

I've installed Evolution 3.44.1-0ubuntu1 from the proposed updates and text now displays background as expected. This is resolved for me.
