RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

reproducer to test on Dark Breeze theme

Description of problem:

Shrink the window to its minimum Height, observe multiple GTK errors on standard error:
(TextScrollbarErrors:23242): Gtk-CRITICAL **: gtk_box_gadget_distribute: assertion 'size >= 0' failed in GtkScrollbar

Follow up to bug 
https://bugzilla.redhat.com/show_bug.cgi?id=1873488
Seems to be fixed through patch

https://gitlab.gnome.org/GNOME/gtk/-/commit/25879ea37e8918a28187dd382e7704051a38f011#bfe7eff23cee77815e1073464071c3f535b7e6f1

But issue is still seen if window is shrinked to minimum height.
logs are filled if error is triggeredd once.


Version-Release number of selected component (if applicable):

RHEL RHEL 9 with GTK3 version:
gtk3-3.24.31-2.el9.x86_64
Dark Breeze theme


How reproducible:
Always

Steps to Reproduce:

1.  g++ -g text_scrollbar_errors.cpp  pkg-config --cflags --libs gtk+-3.0  -o TextScrollbarErrors && GTK_OVERLAY_SCROLLING=0 ./TextScrollbarErrors
2. Shrink the window to minimum height.

Actual results:
(TextScrollbarErrors:23242): Gtk-CRITICAL **: gtk_box_gadget_distribute: assertion 'size >= 0' failed in GtkScrollbar

Expected results:
No errors
Additional info:

Eclipse uses a custom widget 'Swt-Fixed', I believe in some cases widgets are created "very small" and then they are expanded to window size or comparable size. Though its not uncommon to have a view that has the same height as the the scrollbar slider, at least for our theme (since the minimum scrollbar slider height is about 3 rows of text, reducing the height of a view with a text editor to about 5 rows of text already causes the issue).
