Bug ID: 1353863
Summary: [Wayland?] Lots of warnings when running eclipse
Product: Fedora
Version: 24
Component: eclipse
Assignee: akurtako(a)redhat.com
Reporter: rhbz(a)genodeftest.de
QA Contact: extras-qa(a)fedoraproject.org

Description of problem:
Version-Release number of selected component (if applicable):
eclipse-swt-4.6.0-0.6.git201605092000.fc24.x86_64
eclipse-platform-4.6.0-0.6.git201605092000.fc24.x86_64
gtk3-3.20.6-1.fc24.x86_64
How reproducible:
always on wayland. Not sure on x11 backends: warnings don't occur, but I guess
they are just suppressed.
Steps to Reproduce:
1. start a terminal in a gnome+wayland or weston session
2. start eclipse
3. watch stdout/stderr
Actual results:
Dozens of warnings. Most of them are printed more than once. For example:
Gtk-WARNING **: Negative content width -6 (allocation 1, extents 4x3) while
allocating gadget (node toolbar, owner GtkToolbar)
Gtk-WARNING **: Negative content height -3 (allocation 1, extents 2x2) while
allocating gadget (node toolbar, owner GtkToolbar)
Gdk-WARNING **: Couldn't map window 0x7f448aa02730 as susburface because its
parent is not mapped.
Gtk-WARNING **: Allocating size to GtkBox 0x7f448a198cf0 without calling
gtk_widget_get_preferred_width/height(). How does the code know the size to
allocate?
Gtk-CRITICAL **: gtk_box_gadget_distribute: assertion 'size >= 0' failed in
GtkScrollbar
Gtk-WARNING **: Allocating size to GtkToolButton 0x7f448aaf4cd0 without calling
gtk_widget_get_preferred_width/height(). How does the code know the size to
allocate?
Gtk-WARNING **: Negative content width -1 (allocation 1, extents 1x1) while
allocating gadget (node trough, owner GtkProgressBar)
Gtk-WARNING **: Negative content width -1 (allocation 1, extents 1x1) while
allocating gadget (node trough, owner GtkProgressBar)
Expected results:
Less warnings. Ideally none at all, but we don't live in an ideal world …
Additional info:
I can only reproduce this issue on wayland Gdk backends, but I think it is also
present with x11 Gdk backend though Gdk/Gtk doesn't mind reporting this stuff
to console.
