Thanks for this very complete report Walter. It looks like this might be an upstream bug that affects thunderbird when running natively on Wayland. Would you mind reporting it in the upstream tracker (https://bugzilla.mozilla.org/enter_bug.cgi?product=Thunderbird) and sharing the link to it here?

The '"Thunderbird Mail" is not responding' pops up, and there is no option but to 'Force Quit' (because 'Wait' isn't helping). This does not happen for every move. But yesterday when sorting my INBOX, it happened more than 5 times in total. DESCRIPTION ----------- When moving mail, - I select one or more from the middle pane; - drag it/them to the left (folder pane). - There, I hover above the right folder and wait for it to highlight. - Upon highlight, I release the mouse. Normally this moves the e-mail(s) to that folder, but now I get a deadlock in about 1 out of 20 moves. On Focal, I used all versions, including - 1:91.7.0+build2-0ubuntu0.20.04.1 - 1:91.8.1+build1-0ubuntu0.20.04.1 - 1:91.9.1+build1-0ubuntu0.20.04.1 On Jammy, I'm at: - 1:91.9.1+build1-0ubuntu0.22.04.1 The first time I noticed this issue, was while I'm on Jammy. But, I hadn't cleaned my mailbox in a while, so it _might_ be related to the Thunderbird version. Although I my money would be on the version in conjunction with Jammy (Wayland?).) OBSERVATIONS ------------ - My INBOX is not big. It contained 2,500 mails or so. (And very few large e-mails.) The destination folders aren't particularly big either. And I didn't see a pattern related to which destination folder. - When starting thunderbird from the command line, I get lots of these: ###!!! [Parent][DispatchAsyncMessage] Error: PClientManager::Msg_ExpectFutureClientSource Processing error: message was deserialized, but the handler returned false (indicating failure) IPDL protocol error: Handler returned error code! ###!!! [Parent][DispatchAsyncMessage] Error: PClientManager::Msg_ForgetFutureClientSource Processing error: message was deserialized, but the handler returned false (indicating failure) Unsupported modifier, resource creation failed. XXX: resource creation failed IPDL protocol error: Handler returned error code! (But I have no idea what they mean, or whether those log lines were emitted in the Focal version.) - Thunderbird runs as a family of three: /usr/lib/thunderbird/thunderbird \_ /usr/lib/thunderbird/thunderbird -contentproc -childID 1 -isForBrowser -prefsLen 1 -prefMapSize 263514 -jsInit 285636 -parentBuildID 20220520005021 -appdir /usr/lib/thunderbird 549186 true tab \_ /usr/lib/thunderbird/thunderbird -contentproc -childID 2 -isForBrowser -prefsLen 1 -prefMapSize 263514 -jsInit 285636 -parentBuildID 20220520005021 -appdir /usr/lib/thunderbird 549186 true tab - Main PID has 248 threads, child 1 has 23, child 2 has 22.
