Pasting of multiline text adds extra newlines

[raorn]

Steps to reproduce

Copy multiline text from a terminal or text editor:

111
222
333

Paste into telegram desktop message input box

Expected behaviour

111
222
333
_

_ - cursor position

Actual behaviour

111

222

333

However, this does not happen iff multiline text is copied from code-formatted message from telegram itself.

Same story on Ubuntu 22.04.4 LTS with Telegram Desktop 5.2.1 - 5.2.3.

[saddedmoroz]

Tg 5.2.3 x64 portable windows version, copy/paste works as expected

[raorn]

5.0.4 Fedora Liniux 39 - works as expected

[Aokromes]

can't reproduce on 5.2.3 static binary running on fedora 40 nor on ubuntu 23.04..

[perpostas]

The same issue is on Telegram Desktop v5.2.3
Ubuntu 22.04.4 LTS

[ilya-fedin]

Can't confirm, there's no such issue

[sejtevgenij]

facing the same issue on Ubuntu 22.04.4 LTS, Telegram v5.2.3 (Linux x64 static binary)

[sejtevgenij]

Fedora 40, Telegram v5.2.3 (Linux x64 static binary)

• Wayland Session: the issue is not present
• Xorg Session: the issue is present

[ilya-fedin]

Can't confirm on Wayland nor X11.

Xorg session (xubuntu)

[cyberknight777]

can confirm on Telegram Desktop v5.2.3 on Arch Linux running X11 with i3WM. However it only happens with terminals, if I copy from my editor (GNU Emacs), it's fine.

This seem to point to the fact that steps to reproduce aren't full. As I try with a random text editor/terminal and can't reproduce while some exact text editor/terminal has to be used?

FWIW, it happened on both lxterminal and xterm.

[ilya-fedin]

Can't reproduce with the first one and can't copy from the second one at all

[ilya-fedin]

Maybe you folks have some kind of clipboard manager that is not compatible with Qt 6 (the toolkit tdekstop is based on)?

It also happens on tilix btw.

[ilya-fedin]

As tdesktop doesn't handle clipboard, this should be a bug in either some system component or Qt. And other Qt applications using the same Qt version (Qt 6.7.2 for tdesktop 5.2.3) should be affected just as well (but it could be a problem to get other applications using Qt 6.7.2 to test depending on the distro)

[ilya-fedin]

But I can't even confirm such a bug even exists yet, though.

[ilya-fedin]

What I mean is, this report will be closed either because no developers able to confirm or because it's not a tdesktop bug as clipboard is not tdesktop's area of responsibility so nothing could be done on it.

[ilya-fedin]

no, can't confirm with tilix either

[cyberknight777]

Idk how else could I help reproduce this tbh.

[cyberknight777]

Okay I have verified something.

It does not happen on v5.1.7. Whatever changed in tdesktop started happening since v5.1.8

[cyberknight777]

@raorn can you confirm this?

[sejtevgenij]

Okay I have verified something.

Have checked the same and can confirm it.

Also I've tried different applications as copy source
Telegram v5.2.3, Ubuntu 22.04 LTS, X11:

• Gnome Terminal, Tilix, Gedit - the issue is present
• Kitty - the issue is not present

I observe the same behavior in Telegram Desktop 5.2.3. I use Ubuntu 20.04.6 LTS. It occurs when typing multi-line text with breaks as a single line before inserting it, e.g. in Notepad.

After pasting into the message input field in Telegram, each single line line break is replaced by three lines.
