Console message "Gtk-WARNING gadget with negative dimensions"
alain_bkr I have also this message on Linux (ubuntu 20.04) , with 3.0.beta1
For example https://www.hostedredmine.com/issues/853927 is about such an error, and still open.
Work version of #44995 applied, I got some info about appearance of that message (at least one path - there might be more than one to it)
The call chain begun from real_timer_callback() -> blink_active_unit() -> unqueue_mapview_updates().
Well, calling unqueue...() from a timer function is risky - who knows what state the UI is at that specific moment.
Comment in blink_active_unit():
I've been testing some changes, but am not really sure of they 1) work and 2) don't introduce other regresions.
At this point I think we wait over 3.0.4 release, and then try to fix this in the very beginning of 3.0.5 cycle, to have it in testing for the entire cycle.

I think it at least reduces the frequency of the error message, so closing this ticket now that the patch has been pushed. Let's open a new ticket if there's further cases with similar error message.
The following error messages appears on the console during a Freeciv S2_6 game:
I saw 4 copies of this message during a test game of about 50(?) turns, lasting 20(?) minutes. 3 occurrences happened near the beginning of the game, and 1 midway through the game. I do not know what game activity provoked them.
Freeciv version: S2_6 branch, commit 9cd08cd4cbe3dc201703e3609d42723f69065cca .
Client: freeciv-gtk3.22, "Freeciv version 2.6.4+ gui-gtk-3.22", on macOS 10.13.6 High Sierra
Game: local server, Civ2Civ3 rules, AI level Normal, Hexagonal tiles, no North-South wrapping, otherwise default settings.
This obviously looks like a GTK3 name. The name "GtkNotebook" occurs 8 times in client/gui-gtk3.22/* in the S2_6 branch source code.
Sorry, this not a well-isolated bug situation. I just want to get a placeholder into the bug list, for future refinement and isolation.
Expected behaviour:
Freeciv code never draws a GTK gadget with negative dimensions. No messages like this are printed to the console during games.
