Debian Bookworm 2.13 Remote Desktop Manager crashes and clipboard corruption using clipboard integration for RDP sessions

OS and desktop environment

Kernel 6.1.43-amd64

When an RDP session is established using RDM, RDM may freeze and eventually silently exit after copying text to the clipboard. Frequently, the copied text, if successfully copied, will paste into the RDP session in a corrupted form, often consisting of seemingly random unicode characters. It seems that this clipboard data corruption sometimes triggers a sequence of characters that causes RDM to crash. Furthermore, if the text that caused RDM to crash is left in the clipboard, relaunching RDM will result in the application immediately crashing on launch until the clipboard is cleared. The text in the clipboard on the Linux host remains clean and uncorrupted throughout this occurring from the perspective of the Linux host.

I plan to try reproducing this issue on Debian Trixie when I get a chance. I will post results here when I do that. Also, I will capture screenshots of the clipboard corruption and upload them as well.

Hi shawniverson,

We have fixed some text encoding issues in version 2026.1.0.8. Would you mind updating and telling us if this issues still occurs? That would be much appreciated.

Best regards.

It appears after updating to 2026.1.0.8, the problem has lessened. However, it has not eliminated the problem. I currently have content in the local clipboard that caused my RDP sessions to crash and that is crashing RDM upon launch. I am unable to determine if the text is garbled since I cannot successfully launch RDM with this content. Clearing the local clipboard allowed RDM to launch again normally.

"There were problems decrypting some credentials.
Click OK to copy the details to the clipboard.

Credentials profiles:
REDACTED: REDACTED (File) [Failed to decrypt using REDACTED credential]
"

The quoted text above is what was in my clipboard. Had to redact some info in it.

Thank you for trying it in 2026.1.0.8 for us. I will open a ticket to investigate this issue. We will update this thread if we have news to share or when we've resolved this issue.

Best regards

Looks like issue isn't resolved, here's a garbled clipboard entry using copy/paste in an RDP session:

I can't seem to be able to reproduce the issue you're experiencing... Does it happen regardless of what kind of text you copy (markdown, plain text, etc)? If not, in what kinds of contexts does it occur?

It doesn't seem to matter what I am copying, and I am wondering it is very specific to me using KDE on Debian.

I'll also add it is random. I can sometimes go all day without issues, but then randomly it will occur. It also looks like it can happen in both directions. I've had corrupted text inside of my RDP session from text coming from my Linux host and corrupted text in my local clipboard coming from the RDP session.

In fact, it just happened again, and for giggles I copied my clipboard out and repopulated it since it wasn't garbled. I was able to then launch RDM without it crashing with the same clipboard contents, which is really odd and supports the idea that it is happening intermittently.

Hello,

Thanks for the detailed follow-ups, this is really helpful.

I don’t believe the issue is related specifically to your setup (Debian + KDE + Wayland). I’m running a very similar environment on my end and haven’t been able to reproduce the behavior so far.
That said, given the intermittent nature and the clipboard involvement (especially with corruption persisting across launches), I’m going to try to actively reproduce this on my side using similar conditions.

I’ll keep you updated as soon as I have any findings or if I manage to trigger the issue.

Thanks again for your patience and the thorough testing it’s really appreciated.

Best regards,

Carl Marien

I'm going to try various things to try to isolate the problem. I had the clipboard corruption happen this morning, but this one didn't crash RDP. I copied the same text 3 times inside the RDP session, the first two times the corruption happened identically (same garbled text both times), and then it was fine the third time. I was only observing the local Linux clipboard. I'll observe both next time.

Hello,

I spent quite a bit of time this weekend trying to reproduce the issue in my homelab under similar conditions, and unfortunately I wasn’t able to trigger it even once all clipboard operations (including repeated copy/paste through RDP) worked as expected on my side.

Given that, it does seem like this might be something more intermittent or environment-specific, which makes it a bit trickier to pin down.

Please keep sharing any patterns or observations you notice especially if you manage to narrow down any specific conditions.

Thanks again for your detailed testing, it really helps.

Best regards,

Carl Marien
