The welcome dialog randomly fails to appear
Tested with servers running on a fresh Git build (5283dbcf) and with today's autobuild client.
Most of the time the welcome dialog doesn't appear on connect, and pressing "i" later brings up the "old" textbox welcome dialog. Sometimes everything works, the welcome dialog (in a window) appears on connect, and pressing "i" later brings up the window again as expected.
I tried reverting 7b988756 on the server then on the client, but it looks like it's not the cause of the issue.
I connected a few times to the 7sins servers and it seems to work there, so it's possible that my server config is the cause of the issue.
