No Longer Copies from Remote Desktop to Host

[GGitMe]

Describe the bug
With CopyQ installed on a host Windows computer, when copying in a Remote Desktop window, CopyQ doesn't seem to add the information to the item list, making it unable to copy to the host. When copying, the notification will say:

Data Copied

If the Remote Desktop window is closed, a notification will pop up saying:

Data Copied

When opening the "Clipboard Content" window, the data will be visible there, but it's not on the item list, and when opening a context menu to paste the data, the paste command is grayed out.

There is no problem copying from the host to the remote desktop.

To Reproduce
Copying or cutting anything to clipboard in a Remote Desktop window and then trying to paste it on the host.

Expected behavior
Using the clipboard between the host and Remote Desktop the same way it is used when just working in the host.

Version, OS and Environment
Windows 11 Pro remote computer and host.

The bug has been happening since CopyQ version 9.0.0, and is not present in version 8.0.0. In 8.0.0, when using the clipboard between a remote computer and the host, CopQ behaves the same as when using the clipboard entirely within the host.

Additional context
I don't know if they are related, but there are entries in the log like this:

Warning [2025-04-08 17:53:19.413] : [kf.notifications] QtWarning: Couldn't find the notification in m_notifications. Nothing to close.

I think this could be some problem with the new Qt version.

You can try if it works in the old Qt 5 version - I provide the builds here: #2636

Better test it with the portable version, or backup your configuration, since Qt 6 has some incompatible changes for the INI files.

I confirm has the same problem.
I'm using Windows 11 with CopyQ version 10.
If I copy the text in RDP remote client, it won't appear in the CopyQ clipboard list.

I also test your new build here: #2636 (comment)
It is the same problem. I noticed when I copy the text from RDP, it acutally show as "Hidden" item in title bar of CopyQ. Check the current clipboard content show as below screenshot:
