The equation editor has a black background and the font is also black. This make it completely unusable.

I have tried to switch to a light theme but this doesn't fix it. What I managed to do is to change all the background colors I could find to something like light grey 25% and even went and installed a Light Grey theme.

In my opinion, there should be a specific section where the editor colors can be modified.

My system is running EndeavourOS with KDE and wayland.

Delete or rename your LibreOffice user profile. ~/.LibreOffice

Launch LibreOffice again.

Navigate to Tools -> Options -> Appearance panel.

Use the 'Add more themes' button, and select the "Light Application Colors" extension (marked >= 25.2).

The drop list box of themes will now have both 'Automatic' and 'Light Application Colors' select the light application colors theme.

Do not change the Options: System, Light, Dark radio buttons. Leave it on System.

OK out to apply.

Restart LibreOffice.

Any improvement?
