Comment 2 Philippe Makowski 2013-12-27 16:15:37 CET

investigating I found that it is most likely a _gtk_ bug. The reason it si visible in QtCurve and oxygen-gtk is because they both use the "appears-as-list" option to display combobox entries. 

https://bugs.kde.org/show_bug.cgi?id=326424

the workaround indicated in the bug report is working
How can we proceed ?

Comment 3 Philippe Makowski 2013-12-27 16:35:48 CET

it is a gtk2 bug
see https://bugs.kde.org/show_bug.cgi?id=326424

Comment 4 Philippe Makowski 2013-12-29 20:13:18 CET

I don't have clear solution for this, it is not Meld specific and depend of the theme used oxygen-gtk or QtCurve seems affected  because they both use the "appears-as-list" option to display combobox entries, only workaround as describe in https://bugs.kde.org/show_bug.cgi?id=326424 :

For oxygen, edit the normally already existing file "/usr/share/themes/oxygen-gtk/gtk-2.0/gtkrc" and change GtkComboBox::appears-as-list = 1 into GtkComboBox::appears-as-list = 0 

For QtCurve-Gtk, the option (in the config file) is called `gtkComboMenu`(set it to true)

Comment 6 Hugo Pereira Da Costa 2014-01-10 09:29:29 CET

not an oxygen-gtk bug

Comment 7 Hugo Pereira Da Costa 2014-01-10 09:39:50 CET

in any case, cannot reproduce with latest cauldron.
most likely this got fixed upstream (meld or gtk). Certainly not in oxygen-gtk.
Please close if confirmed

Comment 8 Dick Gevers 2014-01-10 22:24:18 CET

Well stg fixed it; consciously or not.

Resolution: (none) => FIXED

Comment 9 Philippe Makowski 2014-02-16 21:07:49 CET

I reproduced the bug in fresh Mga4
the only correct fix is what I said in c#4

For oxygen, edit the normally already existing file "/usr/share/themes/oxygen-gtk/gtk-2.0/gtkrc" and change GtkComboBox::appears-as-list = 1 into GtkComboBox::appears-as-list = 0

Status: RESOLVED => REOPENED
Resolution: FIXED => (none)

Comment 10 Nic Baxter 2016-02-09 10:39:37 CET

I can't reproduce in either mga5 or cauldron so I assume this has been fixed in the last  2 years

Comment 11 Thierry Vignaud 2016-02-11 11:06:00 CET

We eventually killed Oxygen-gtk as it has many issues with gtk+
