You say "drag-n-drop sometimes fails to work when moving messages. I attempt to drag a message (or a collection of messages) from one folder to another, but the attempt to drag fails and nothing happens".
In https://bugs.launchpad.net/ubuntu/+source/thunderbird/+bug/1977715 I also report that it sometimes fails. But in my case Thunderbird becomes completely unresponsive. Could be related. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to thunderbird in Ubuntu. https://bugs.launchpad.net/bugs/1934243 Title: thunderbird drag-n-drop move messages fails on Wayland Status in thunderbird package in Ubuntu: Confirmed Bug description: On Ubuntu 21.04 when I use Thunderbird, drag-n-drop sometimes fails to work when moving messages. I attempt to drag a message (or a collection of messages) from one folder to another, but the attempt to drag fails and nothing happens. This occurs when I use the default (Wayland) login. The problem does not occur when I use X.org login. The problem is intermittent; it may take a few moves for the failures to start occurring. I reported this issue in bug#1934185 but that bug report is primarily about Ubuntu Dock and I was asked to file a separate bug report about Thunderbird. To file this bug report, I ran "ubuntu-bug" under X.org but the bug actually occurs only under Wayland.
