G_ENABLE_DEBUG is tied to the meson builttype property, so building with "plain"
results in G_ENABLE_DEBUG not being defined and the GTK_DEBUG env var just gets ignored
for that build.
Since it can be confusing that GTK_DEBUG has no effect print a warning message instead.
Fixes#2020
In the unlikely case that GTK is "embedded" with other toolkits
(hi, Mutter), GTK will clobber the embedder's AtkUtil implementation,
leaving its own a11y in a broken state.
AtkUtil is not meant to be overridden by multiple toolkits within a
single client, so the most sensible thing to do is stay away from it
if that is the case. This helps the embedder's a11y to win.
Fixes Clutter a11y in Mutter after xwayland-on-demand, process
startup used to be in a fixed order so that Clutter's a11y would
eventually win, but x11/gtk startup is now asynchronous and able to
happen at a later point.
Closes: https://gitlab.gnome.org/GNOME/gnome-shell/issues/1687
gdk_screen_get_resolution() can return -1 when the resolution is
unknown. Catch that case and use the default resolution of 96, like in
every other case.
Fixes#2119
We need to take the device scale into account, like it is done in
gdkwindow.c.
This fixes wrongly placed DnD surfaces in scaled contexts on X11
as well as Wayland.
We're potentially applying multiple properties during object
construction; we should avoid constantly notifying after setting each
one, and instead coalesce the notifications at the end. In most cases,
the calling code doesn't have access to the instance, so it won't be
able to connect to the "notify" signal anyway, but it avoids a lot of
busy work.
because if there's a tooltip visible then popups fail to show
with the following warning:
"Gdk-WARNING **: Tried to map a popup with a non-top most parent"
This bug affect popups of the form:
1) popups from gtk_menu_popup_{at_widget|at_rect|for_device}()
This can be reproduce with a normal GtkComboBox that has a
tooltip attached (eg. via GtkBuilder 'tooltip_text' attribute).
Also see GtkLabel reproducer from gtk3-demo mentioned in #1785
2) custom popups created with gtk_window_new (GTK_WINDOW_POPUP)
A reproducer that shows this case is a GtkComboBox with
the property 'appears-as-list'[1] set to TRUE (default is FALSE).
Fixes issue #1785
