What happened?

Hi, I've been using Barrier for about a year between my main laptop (with Linux and Windows dual boot) and an old laptop (running Lubuntu) that I mostly use as a second screen.

I'm currently working on my thesis, I have documents in Google Docs open on both laptops (notes on the old one, my thesis on the main one), and I often copy text from one screen to the other.

Recently (I can't remember when, exactly), I've been running into the problem that formatted text (with italics or bold etc.) gets corrupted when copying between server and client. When I copy flat text from a text editor like gedit, it's no problem, and when I paste without formatting (Ctrl + Shift + V), it also works, but then I have to redo the formatting.

I've tested the clipboard bug by copying the sentence: "This is a test sentence." from client to server and vice versa, testing with my server laptop running Linux as well as Windows. These were the results:

The log doesn't seem to show anything out of the ordinary, I've pasted it in the log output field.

I hope I have provided enough information. If there's anything I can try to change in the settings, or any additional information/testing I could provide, please let me know.

Thank you very much.

Kind regards,
Rutger

P.S. I don't really remember from where I installed Barrier. Is there any way I can check that?

I have this problem as well but i dont know if it is relevant. In my case i am copying plain text from a linux machine (client) to a windows machine (server)

If i paste the text in Microsoft Teams( on windows ) then the text glitches out and shows similar symbols.
However if i paste the text in a browser url ( again on same windows ) then it pastes correctly.

I dont know if this is a problem on microsoft teams side, but currently if i am using microsoft teams, i am forced to paste things in a separate app and copy them from there. This same issue happens with images too, when pasted on microsoft teams.

I have the same problem that @redsigma commented. My solution was to paste the text in Teams directly with Ctrl+Shift+V. Not sure why, but it works.

@redsigma commented on GitHub (Jan 9, 2025):

I have the same problem that @redsigma commented. My solution was to paste the text in Teams directly with Ctrl+Shift+V. Not sure why, but it works.

Thanks for the info. It seems teams added now a plain paste feature in the dropdown
