Image clipboard not working

[dbarnathan]

Describe the bug Barrier version 2.3.3: Text clipboard is working between windows 10 home pro 64 bit. (Server), and Mac Mini M1 late 2020 (Client). Image clipboard is working when the screenshot is taken on Mac can be pasted to windows. However when the screenshot is taken on windows it cannot be pasted to messages or other applications, the oldest image clipboard is saved to the Mac. To Reproduce

1. Windows+shift+S on server
2. Paste on mac client.

Expected behavior Image to be pasted on Mac.

Screenshots If applicable, add screenshots to help explain your problem.

Please do not link to image hosting sites, as these can be ephemeral. Instead, attach them to the issue.

Desktop (please complete the following information): Windows 10 Home Pro. Apple Mac Mini M1 (latest mac OS big sur build.) Barrier 2.3.3

Add any other context about the problem here. IT had been working before and it randomly stopped working recently I have tried restarting both the client and server and cannot seem to figure it out.

Believe it or not, I have the same issue but found out if I copy again, I could transfer images. It's a pretty bad bug though. Hoping for a fix. Thanks!

I have same issue, can't copy image between Ubuntu20.04 and Win10

[jshelley-xx]

This began happening to me with pop_os(server)/win10(client). I haven't quite gotten it figured out but as a workaround I installed Diodon, then when I want to transfer something I select it from Diodon's tray menu between the copy and paste.

Regarding the issue itself, if I merely Screenshot to clipboard, then go to paste over in windows, I see this in the log:

whereas if I use an interim copy mechanism like Diodon (GNU paint works too), I see something like this:

and in the latter case, pasting over to Windows works fine.

I don't seem to have any problem going the other direction (Win+Shift+S on the client and paste into the ubuntu server).

I'll keep fiddling with it.

Hi guys, I had the same issue ( copy paste Windows 10 > Windows 10 doesn't work). I used it with the windows + maj + s function to past it on the other device. I tryied many things, and one seems to fix it (temporarly ?) : On the Server Barrier : Click on Apply. The copy works again !

[arnholm]

I have the same issue with Image clipboard not working properly Barrier server: Kubuntu 20.04, Barrier 2.3.2 Barrier client: Windows 10, Barrier 2.3.2-snapshot-210c2b70

Image clipboard copy/paste from Windows (barrier client) => Kubuntu: Works OK once, then stops working Image clipboard copy/paste from Kubuntu (barrier server) => Windows: Does NOT work (copies chinese characters)

I tested it by copying images from BraveBrowser and pasting into LibreOffice Write on the opposite machine

[syu-id]

I have very similar problems as with dbarnathan. Copy & paste images from my Kubuntu client to Windows server works fine, the reverse doesn't work.

Windows 10 (server): Barrier 2.3.3 Kubuntu 20.04 (client): Barrier 2.3.3 (installed via snap)

[ussu99]

Similar Problem. Mac Server Barrier Version 2.4.0 Windows 10 Client Barrier Version 2.4.0

• Image Copy via Clipboard from Windows Client to Mac Server works
• Image Copy via Clipboard from Mac Server to Windows 10 Client doesnt work
  • When ssl disabled it works!

I have this issue with Ubuntu 22.10 on both machines. I can copy files and text, but not screenshots. It used to work, but something changed.

[carmex]

same here, Barrier 2.4.0. copying on mac and pasting on windows. a white square of the correct size appears but no image

[flamecopper]

When copy from my server (Macos) to Client (windows 10), I need to copy in word document or paint first, it doesn't appear on the clipboard automatically.

[larrasket]

Same issue with archlinux, both client and server

[kexin8]

I had the same problem【window11 -> macOS 13.4.1 (M2) 】

[skamansam]

same with ubuntu and fedora - fedora to fedora, fedora to ubuntu, and ubuntu to ubuntu

[mrcharles]

Having the same issue. Barrier 2.4.0-release-3e0d758b Windows 11 Client copy, paste to Server Ubuntu 22.04 Barrier 2.4.0-release-0000000 (installed via Ubuntu Software Manager) does not work for images. Reverse also doesn't work. Text works fine though.

[frohro]

So I have been having issues with pasting gnome screenshots, but I found that flameshot screenshots work just fine. Both are Ubuntu. The server is 23.10 and the client 23.04.

[mrcharles]

So just an update that today this is partially working for no apparent reason. Zero system changes on either system. So the bug is definitely rooted in some kind of state or instability; the only thing that's happened is that both machines have rebooted a few times.

I can now paste from ubuntu to windows, but not vice versa.
