Do you have an example image you're attempting to paste?

There is an existing ticket open that may be related to this: https://mattermost.atlassian.net/browse/MM-20822.

Confirmed on Arch Linux, too (package mattermost-desktop-bin from AUR, version 4.3.2-1, kernel 5.4.1-arch1-1)

Can confirm that CTRL+v does not work with MatterMost (using Windows 10).
I can rightclick+paste with text, however, it does not paste images. I believe amyblais is correct, seems that ticket is related to this issue.

Going to be reverting back to v4.3.1 for now..

FWIW, I can copy/paste with Ctrl+Shift+C/V, but it won't work for Cut with Ctrl+Shift+X.

@a25814740 Still unable to copy/paste images using the shortcuts.

I can confirm this on macOS Catalina. I cannot paste with CMD+V, but i can paste with right click->paste.

[ashishpatelmi]

Please back to version Version 4.2.1

This working for me

Paste: Shift + Insert

Mac OX ( I'm not sure )

Paste: Shift + Insert

I can reproduce on Windows 10 with Mattermost Desktop 4.3.2: Ctrl-c and Ctrl-v do not work but Ctrl-Insert and Shift-Insert work. With Mattermost Desktop 4.3.1 it works. On Ubuntu 19.10 it works with Mattermost Desktop 4.3.2.

I found out that the issue happens since the commit fddb891d8dbb32be7fcab75fe482128130e76255. Removing the manual handling of copy/cut/paste keyboard shortcuts in main.js fixes the issue.

Same issue :(

macOS Catalina 10.15.2 (19C57)
matermost 4.3.2 (4.3.2.4230)

command+c (copy)
command+v (paste)
command+x (cut)

not working.

Would you be open to trying if desktop app v4.4.0-rc1 fixes the issue for you: https://github.com/mattermost/desktop/releases/tag/v4.4.0-rc1?

[twistedvip]

@amyblais just downloaded/installed. It fixes the issue for me :) (Win10)

It fixes the issue for me too on Windows 10.

I had the same issue crop up after switching from non-SSL to SSL communication on the server end, switching to the new release client seems to have fixed the issue.

[nyclabels]

I believe this issue may be related to enabling SSL via the nginx proxy- as soon as I enable SSL, it stops functioning, but as soon as I disable SSL, it works. Not using letsencrypt, using local CA-generated certificates.

Using client 4.3.2, installed via MSI, on Windows 10 x64 Pro 1903.

Looks like this happens on macOS too (Version 4.3.2 (4.3.2.4230))

[amyblais]

Would you be open to trying if desktop app v4.4.0-rc1 fixes the issue for you: https://github.com/mattermost/desktop/releases/tag/v4.4.0-rc1?

[nyclabels]

I can confirm the 4.4.0-rc1 client does resolve the issue for me.

The problem is solved with https://docs.mattermost.com/help/apps/desktop-changelog.html#release-v4-4-0 on Win10, Ubuntu 18.04 and current MacOS. Thx for the support.
