These sound like upstream issues, really. The changelog for 91.3.2 mentions a bugfix related to the use of a dark theme, so maybe your problem is fixed there too?
In any case, I'd suggest filing a bug at https://bugzilla.mozilla.org/enter_bug.cgi#h=dupes%7CThunderbird, and once you've done that, please share the link to it here. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1950912 Title: Drop-down Calendar menus unreadable in Thunderbird To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thunderbird/+bug/1950912/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
