Description Elio Maldonado Batiz 2019-02-28 01:36:59 UTC

Description of problem: 
Running Meld on fedora 30 prerelease with GNOME not show a preference menu.  I can not find a way to edit the preferences.

Version-Release number of selected component (if applica
meld-3.20.0-2.fc30.noarch

How reproducible:
Every time

Steps to Reproduce:
1. Install meld
2. Run meld
3. See that the preferences menu item is missing

Actual results:
Preferences menu item is not shown

Expected results:
Expect to see a preferences menu item so I can change the filters

Additional info: I add another fedora spin, such as cinnamon or mate, then I can set the preferences. Later I come back to gnome that the preferences menu is there and can make more changes.

This doesn't occur on f29, where meld is meld-3.19.1-1.f29.noarch.
My systems are Oracle VirtualBox VMs hosted by macOS in case that matters.

Comment 2 Elio Maldonado Batiz 2019-03-01 18:03:24 UTC

Some additional info for when you get a chance to took into this:
- Instead of switching to another spin one can switch to gnome-classic and back.
- I ran into the same problem on the last two releases of Ubuntu.

Comment 3 Elio Maldonado Batiz 2019-03-01 21:33:24 UTC

This problem is likely not due to meld and likely a Wailand issue and probably upstream given that is happens on other Linux distros

Comment 4 Elio Maldonado Batiz 2019-03-02 19:43:15 UTC

Following the info at https://fedoraproject.org/wiki/How_to_debug_Wayland_problems
I ran meld these the ways:
with 'GDK_BACKEND=x11 meld' the Preferences are available.
with 'GDK_BACKEND=wailand meld' Preferences do not show up.

Mistake, no problem there.

Comment 6 Elio Maldonado Batiz 2019-05-18 19:45:50 UTC

Good news, Installed workstation from Fedora 31 Rawhide 20190517.n.0 from
https://fedoraproject.org/wiki/Test_Results:Fedora_31_Rawhide_20190517.n.0_Summary
and don't see the problem any longer. I suspect this was a Wayland problem and not a meld one.

Comment 7 Elio Maldonado Batiz 2019-05-18 22:34:15 UTC

It's also working now in f30 with a fresh install of workstation updated to latest.
