Description of problem: On scrolling the comparison, a stream of GTK errors is output to the terminal where meld was started. Presumably sterr. Version-Release number of selected component (if applicable): meld 3.16.2 How reproducible: 100% Steps to Reproduce: 1. start a 2-way file compare, in background from a terminal 2. scroll down by mouse-grab of the right-hand slider gadget 3. Actual results: repeated lines on terminal: (meld:7157): Gtk-WARNING **: Allocating size to GtkVBox 0x560705026ba0 without calling gtk_widget_get_preferred_width/height(). How does the code know the size to allocate? Expected results: No warnings output
Similar seen from wireshark: (wireshark:12542): Gtk-WARNING **: Allocating size to GtkWindow 0x55c10312f2e0 without calling gtk_widget_get_preferred_width/height(). How does the code know the size to allocate? [note GtkWindow rather than GtkVBox] Possibly a Gtk library internal bug rather than the applications?
I get the same problem with meld. It also prevents jump to "Previous change" "Next change" to work correctly.
I create this bug in meld bugzilla: https://bugzilla.gnome.org/show_bug.cgi?id=771878
The bug I created was a duplicate of this one: https://bugzilla.gnome.org/show_bug.cgi?id=769705 Following is a patch that solves the problem, at least for me: https://bugzilla.gnome.org/attachment.cgi?id=335456&action=diff
ping. Getting awful lot of similar warnings in Fedora 25: (meld:18252): Gtk-WARNING **: Failed to measure available space: The specified location is not supported [...] (meld:18252): Gtk-WARNING **: Allocating size to DiffMap 0x55f7779d07b0 without calling gtk_widget_get_preferred_width/height(). How does the code know the size to allocate? Any expected time to have this fixed? Version: meld-3.16.4-2.fc25.noarch

The change which is reported in the upstream report https://bugzilla.gnome.org/attachment.cgi?id=335456&action=diff appears to be included in meld-3.16.4-4.fc25.noarch Still I also get these messages. (Un)related I found this GTK fix: https://github.com/GNOME/gtk/commit/ddcf47026dbbe58dca3b34c7bb1ec63bb50a861a
This message is a reminder that Fedora 25 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 25. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '25'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 25 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 25 changed to end-of-life (EOL) status on 2017-12-12. Fedora 25 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
