What Operating System are you using (both controller, and any agents involved in the problem)?

RHEL Linux 7.9 controller
(Agents are RHEL Linuxes.)

Reproduction steps

We just upgraded the Jenkins package from 2.332.3 to 2.346.2

Expected Results

I expected the jenkins-material-theme generated via http://afonsof.com/jenkins-material-theme/ to work (look) as it has been for 3 years.

Actual Results

The console output formatting is unreadable, see screenshot attached to https://issues.jenkins.io/browse/JENKINS-67866

The header is messy too: instead the primary color and the company logo chosen when generating the style.css, a black header is seen, sans the usual logo in the left side.

The console formatting bug is a bit inconsistent, there are moments when the console output is displayed correctly. But if I refresh (CTRL-SHIFT-R) the window, the result is always messed up.

Anything else?

As you can see, someone opened a bug report months ago in the official Jenkins Jira:

https://issues.jenkins.io/browse/JENKINS-67866

Which was closed as "Not A Defect" soon afterwards. Also see comments on said Jira issue.

On second thought, this is probably a jenkins-material-theme problem. At least there are issues posted about it:

afonsof/jenkins-material-theme#193

afonsof/jenkins-material-theme#194

The jenkins-material-theme has been abandoned 4 years ago, so its no wonder it won't work with current Jenkins versions. The Material Plugin might be a bit more modern...

And as said elsewhere: This is not a problem with this plugin.
