Cannot copy/paste text from Eclipse to Wayland applications

[weberhofer]

Eclipse should ideally prefer mimetype strings in clipboard and drag and drop targets for both
Wayland and X11, over old-style STRING and UTF8_STRING format strings. Since the wayland protocols
specify that the types passed must be mimetype strings, this results in failed clipboard operations
with other Wayland clients. Mimetype strings like text/plain and text/plain;charset=utf-8 are
widely accepted both in X11 and Wayland.

GTK4 SWT port is already doing so 8595995 . Do you think you can try modifying GTK3 port to do so too?

[weberhofer]

@akurtakov, can you please get directly in contact with the people from Gnome via https://gitlab.gnome.org/GNOME/mutter/-/issues/2448 or https://gitlab.gnome.org/GNOME/gtk/-/issues/5217 as I'm not able to help here?

This still is a problem even with the latest GTK 3.24.35 that includes the additional translation merged on https://gitlab.gnome.org/GNOME/gtk/-/merge_requests/5072

I got this from my gnome issue: https://gitlab.gnome.org/GNOME/mutter/-/issues/2536#note_1606119

Same issue with KDE apps https://bugs.eclipse.org/bugs/show_bug.cgi?id=579653

[weberhofer]

IMHO the problem even got worse with Eclipse 2022-12.

[lalmeras]

Same here ; Eclipse 2022-12 copy paste does not work. Same with Dbeaver 22.2.5.202211202223 (eclipse-based).

Same applications with GDK_BACKEND=x11 works fine.

[lalmeras]

After some digging : gtk 3.24.35 tries to fix this issue, but fails to do so: https://gitlab.gnome.org/GNOME/gtk/-/merge_requests/5072

Another issue that seems to be related with this issue and is merged into gtk 3.24 but not released : https://gitlab.gnome.org/GNOME/gtk/-/issues/5397

On my side, I try the proposed patch and it solves the copy issue (from eclipse/dbeaver to firefox). So gtk 3.24.36 release should improve the situation.

[ichbindannmalwegmann]

Now gtk3-3.24.36-1 (https://bugzilla.redhat.com/show_bug.cgi?id=2151603) it works.

[mickaelistria]

I confirm gtk3-3.23.36-1 fixes the issue here on my Fedora 37!

[akurtakov]

Closing as this has been fixed in latest gtk3 and changing swt gtk3 clipboard implementation has to potential to destabilize things and gtk4 port has it working with the new approach already.
