Clipboard not working with longer text (VM)

[fmigneault]

Bug Description

Copying a value longer than 1234567890123456789 from the local instance and trying to paste it on the remotely connected VM side does not paste the updated content (either nothing pasted, or the previous copy of shorter text is pasted). Doing the inverse operation (copy on remote, paste locally) does not work regardless of content length.

It seems the clipboard fails to store the text for transfer.

How to Reproduce

Copy 1234567890123456789 from local and paste on remote anywhere. This should work.
Copy 1234567890123456789xxx from local and paste on remote. Does not work or pastes the previous 1234567890123456789.

Expected Behavior

Copied text should be pasted regardless of length (or at least up to a reasonably large size) to allow transfer file configs and such.

Operating system(s) on local side and remote side

Windows 11 local, Ubuntu 22.04.6 LTS remote

RustDesk Version(s) on local side and remote side

nightly "1.2.4" on 2023-12-13

Hello, Thanks for reporting but I could not reproduce it on:
mac -> ubuntu wayland & x11 both
windows -> mac
[I ran out of space for VMs so currently can't test windows -> ubuntu. I will free up some space soon and test it 😅]

• Here's mac -> ubuntu wayland; recently introduced clipboard feature:

Hi @sahilyeole
Thanks for looking into this.

It seems the result is very inconsistent.
I made a video to demonstrate various combinations of right-click copy/paste vs CTRL-C/CTRL-V and to/from local/remote.
I recorded the audio so we can hear when I do the CTRL instead of right-click.
Sometimes something is pasted, but it seems to be an older clipboard text in some cases.

@fmigneault please confirm if it is Wayland on remote side.

Wayland is disabled. Using X11 only.
