Description Cor Blom 2024-04-25 11:59:57 UTC

In a mail to lyx-devel it was reported that lyx does not start under GNOME Wayland. It does under X.

I have tested sigil and kdenlive, which give the same behaviour. They seem to start, but do not show a window.

They work correctly under kde plasma.

To reroduce:

1. Login on gnome wayland

2. Start lyx, sigil, kdenlive from gui.

3. ResultL nothing visible happens. In overview the apps are visible, but without window.

For me, running lyx from commandline (console) does work.

Comment 1 Jürgen Spitzmüller 2024-04-25 12:52:57 UTC

Conformed, and same problem with Qt Creator, Okular and other Qt apps under GNOME wayland. This is a rather new problem (cannot pinpoint exactly the update that triggered it though)

Comment 2 Cor Blom 2024-04-25 14:54:06 UTC

Seems like:

https://bugreports.qt.io/browse/QTBUG-124450

and

https://gitlab.gnome.org/GNOME/mutter/-/issues/3435

is solved upstream

Comment 3 Alynx Zhou 2024-04-26 06:22:10 UTC

Upstream says https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3475/diffs fixes it, but it is a big change and needs to be backport to GNOME 45.

Comment 4 Cor Blom 2024-04-28 12:11:08 UTC

That fix is part of Gnome 46.1, so when that will arrive in Tumbleweed it should be fixed.

It only happens with Qt 6.7, so it shouldn't affect Leap, which will have 6.6. So I don't think any backporting is necessary.

Ah, yes, thanks.

Comment 6 Cor Blom 2024-05-06 08:51:16 UTC

GNOME 46.1 is now in Tumbleweed, so this should be fixed.

Comment 7 Jürgen Spitzmüller 2024-05-12 07:44:48 UTC

It's not fixed for me with Qt Creator (but with the other affected apps).

I cannot reproduce that. Qt Creator does start and show a window for me.
