confirmed

Thankyou. I’m aware of this and the stuff @Quy mentioned in the original post. I’m currently on holiday but will address this as soon as I can when I’m back (on Friday).

In the meantime if anyone else is interested in solving this specific one before I get back. In most these places we’re using this action variable which is supposed to be blue. So we need to figure out in J4 why it was white in most cases!

there is a variable that is not defined causing issues

var(--bg-color);

looking at the code before the pr this was always
$white;

#41615

First PR (fixes the 4th screenshot here)

#41626

Second PR fixes the 3rd screenshot for the form selects

#41627

Third PR fixes the 1st screenshot for installation tables

@wilsonge Do the 3 PRs #41625 , #41626 and #41627 together fix this issue? or is there something remaining?

Background of menu item lists (screenshot 2) still left to fix

Final fix here #41772
