I am using Evolution with F35, Gnome 41.6 and Wayland. In the past it occasionally happened that Evolution did not show the content of a mail when I open it in a separate window. Sometimes I had to give it several tries until the content is displayed. This symptom is now getting more worse, so most of the mail can not be read when opening them in s separate window. Curious enough: the mail preview window displays the content of a mail (so I can assure that the mail is not empty) and also opening a mail with option ‘reply’ or ‘forward’ displays the content at the first try. But selecting a mail and pressing ‘enter’ or double-clicking a mail or ‘Ctrl+O’ results in opening a new window and displaying an empty mail.
Any hint? Is there some kind of cache in Evolution that is worth to clear?
I don’t have a solution for you, but I share your frustration. I’ve been away from Silverblue for a while, but I’m planning to install it on a new X1 Nano that’s arriving this week. One of the things that frustrated me about Silverblue was the lack of a really good email client. Best solution was Thunderbird with the Exchange plugin (that you pay for) but its hardly ideal. I am hoping Microsoft makes their Outlook PWA available for Linux very soon.
In between I upgraded to F36 and install evolution 3.44.2 rpm, because I was not able to get flatpak 3.44.2 . Seems to be a mixup on flathub, they ‘offer’ 3.44.2 but deliver 3.42.4.
Anyway: rpm 3.44.2 now works fine for me.
