Likely already fixed as part of #812. Try r22519 or later.

It doesn't look resolved to me:

xpra-server is Ubuntu 16.04.6/r22647, but session is old (I don't remember when it was started, xpra info x | grep -iP 'r\d+' does not help)

Also "now":
I know it's no news that clipboard is broken, but now Ctrl+Shift+C on a gnome-terminal empties both clipboards (local and remote AND middle-click buffer).

I know it's no news that clipboard is broken
It is, clipboard is supposed to be fine.

r22449
That's too old and this stacktrace is probably already fixed in newer builds.
As for losing clipboard contents on exit, this was already discussed in a different ticket.

Replying to [comment:3 Antoine Martin]:

r22449

Same with r22633-attaching-client

As for losing clipboard contents on exit, this was already discussed in a different ticket.

Would you please add the ID here?

However, I am not talking about "any" exit:

Select text in win10 xpra-client gnome-terminal (ubuntu 16.04.6)

Ctrl+Shift+C

Switch to e.g. win10 VS Code

Ctrl+C

(Notice no text is coming out)

Switch to win10 xpra-client gnome-terminal (ubuntu 16.04.6)

Open e.g. nano

Ctrl+Shift+V

(Notice no text is coming out)

mouse-middle-click

(Notice no text is coming out either)

I am seeing problems with the MS Windows client where the first clipboard update doesn't take. Copy the same text again and it does paste properly.
The -d clipboard output shows the exact same data both times!
set_clipboard_text('somestring').

Fixed in r22796: we just retry a few times until MS Windows accepts the value!
(no idea why waiting a few milliseconds helps, but it does)

See also #2309: clipboard data type from MS Windows clients was invalid.

New beta builds posted.

If you still have problems, please include the -d clipboard output.
If not, then please close this ticket.
