Attachment: original text

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:81.0) Gecko/20100101 Firefox/81.0

Steps to reproduce:

I composed a new e-mail in plain text mode.

Actual results:

Thunderbird adds additional newlines and spaces to the original text.

thunderbird_test.txt
the original text which I pasted into the "Write" dialog

thunderbird_test_Write.txt
I get this from the dialog when I perform "Select All" and "Copy"

thunderbird_test_Sent.txt
I get this in my "Sent" folder ("Select All" and "Copy")

thunderbird_test_Inbox.txt
I get this in my "Inbox" ("Select All" and "Copy")

Expected results:

The original text should not have been modified.

I don't have any addons. I did the restart and ran Thunderbird in safe-mode. The problem stays the same.

Can you select More > View Source, then copy and paste the section from your message in your Sent folder, like this example from my Sent folder?

Hello!

I can't reproduce the issue using 78.4.3 on Windows 10.

I did "View > Message Source" from the menu bar. Looks like each newline character gets an additional newline character.

That's weird. I pasted the source into "Add Comment". "Save Changes" cleared the newlines. Please see the "Sent source" attachment.

Well, you're not accidentally composing in HTML.

I don't know why you are seeing that.

When I compose in plaintext I don't have a space between lines unless I press “Enter” twice. Which is what I did for the test in comment 6.

This is from my Sent folder and a copy and paste for the reply.

This is a test.
This is a test line 2.
Same here.

I think I found the problem. When I enter text directly (via keyboard) there is no problem. If I paste text from somewhere else the problem arises. It looks normal in the composition window, but gets sent incorrectly. Even copying and pasting text from Thunderbird itself creates the problem. Thunderbird doesn't seem to be compatible with the Gnome "clipboard". If I recall correctly the first broken version was "78.3.2".

This only affects plain text email on Wayland. GNOME or anything else on X seems ok.

Reproduction steps do not require you to send any email.

1. Type a message with a few newlines, eg

test
test
test

test after line
end

2. select and paste into non-HTLM email body
3. Ctrl-A + Ctrl-C + Ctrl-V
4. see 3

For me, the last working version was:
MozillaThunderbird-78.5.0-3.107.1.x86_64

The first broken version was,
MozillaThunderbird-78.6.0-8.3.1.x86_64.rpm

So it may need some additional bisecting but the definitive component here is Wayland. On X, there are no issues.

Additionally to Comment #12, the extra "hidden" new lines are inserted on paste but show up in the keyboard on a copy. So every time you do a cut to the keyboard you see the additional new lines but they are actually inserted on a paste.

Ctrl-A
Ctrl-X
Ctrl-V

is nice way to see it.

My Fedora 33 Workstation Gnome is "Window Protocol x11" for my Thunderbird 78.8.1 installed from Thunderbird.

I have the same problem on openSUSE Tumbleweed with Wayland, Gnome 40.1 and TB 78.10.0.

Comment 16

[Martin Liška]

May I please ping the issue. It's pretty annoying and apparently happens both on Fedora and openSUSE, both are using Wayland.
Can please anybody take a look?

Hmm, I can confirm that officially built 78.10.2 works fine. While openSUSE Tumbleweed is broken (equal version).

Reporter, how is version 91?

Comment 19

[Markus Goppelt]

Version 91.3.2 works fine.
