Compose window is dark, but the theme is light

more options

After Thunderbird updated itself to 91.3.1, now the text area of the compose window is dark, even though the theme I'm using is light.

I've tried the standard themes (System, Light, Dark), and my own orange theme, and the text area of the compose window is dark in all of them.

Is this a bug that Mozilla will be fixing?

Problem solved. I was using the dark theme in Windows 10. When I switched to the light theme, the Thunderbird compose window is now white.
