Wayland: Copy and paste issue

[Expore-it-all]

Is there an existing issue for this?

Problem description

This is my first time posting an issue on Git Hub for this project, if I have missed anything please let me know.
Hi all, I have been using Freecad on Linux and after creating a body I wanted to copy and paste it like I have been able to do so on windows. but I have found that I am getting an error.

Here is the error I am seeing for it whenever I try to copy and paste through the context menu or shortcut keys.

20:13:43  (qt.qpa.clipboard) QXcbClipboard::setMimeData: Cannot set X11 selection owner

I can copy and paste text normally but trying to do so on a body causes this. I have a hunch it is because of Wayland and XWaylandBridge Issues, though Im not 100% sure on this.
I have attached a video of this in action. I tried both context and shortcuts to copy but it still happens.

After some more looking I have found that there is also another Issue related to XWaylandBridge and Copy and Pasting
#10251
Only difference is this is the AppImage Format not flatpack.

Begin rant.

This is a Wayland limitation. Wayland only "supports" (this is generous wording) the primary X copy buffer by design, which it uses for wl_clipboard. Here we have an error that is about the selection buffer, which Wayland has no support for at all.

Usually when a project "fixes" this, they also break middle-click paste for people on X11 (CherryTree is one example). This makes me sad. Properly supporting Wayland's weirdness can be quite involved; see for example rustdesk/rustdesk#5900.

End rant.

Simply rebuilding the Flatpak will probably solve it.

I wish I knew more about coding in the Linux Environment so I could help with this, but my knowledge is quite limited in that aspect. Thanks for letting me know about the issues about it.

Any care to let the FC flatpak packager in on this discussion ?

[djkato]

Please at least in the meantime add an option to "duplicate" under the right click menu while this is broken. Duplicating sketches/bodies etc shouldn't be broken because of the systems clipboard manager. Imo this should be possible inside FreeCAD regardless.(SS from this weeks weekly build)

I would like to give some hints, since i encountered the copy/paste issue by the usage of a workaround for another problem.

My first problem was the 3d display not rendering with console message Couldn't get current GLX context.
The workaround was to add the environment variable QT_QPA_PLATFORM=xcb
This one is generating the copy/paste problem.

I solved the 2 issues by replacing this environment variable by : __GLX_VENDOR_LIBRARY_NAME=mesa __EGL_VENDOR_LIBRARY_FILENAMES=/usr/share/glvnd/egl_vendor.d/50_mesa.json (recipe found for another app getting display problems)

Using Manjaro Unstable / KDE / Wayland / Nvidia / Freecad-git (AUR)
