Attached patch that would produce some logging for debugging purposes - not meant to ever become part of freeciv distribution. For S3_0.
It would be great if ddeanbrown or someone else able to reproduce the problem could get the logs from a run with this patch applied. Launch the client, Start a New Game, W)ait with all the other units until Settlers activate, and then build a city with it (to get a city dialog opened), close the client.
Example output of what I got with 'gui_qt_font_default="Liberation Sans,15,-1,5,50,0,0,0,0,0"' in ~/.freeciv/freeciv-client-rc-3.0

So, it's the adjustment done for the painter that makes the font smaller (14 -> 8). I already were looking at it for another problem in it.

Patch attached. See the commit message on top of it for details. It should make the adjustment to work more "right", but there's no guarantee that even right adjustment would be working well.
ddeanbrown New patch produces much better appearance. Still see the bug #44850 but that's a separate issue.
Even with #44389 patch applied, ddeanbrown reports that the font is not right:
"Applying the patch did not have any affect."
That's on MacOS, where Qt often seems to have behavior different from other platforms (not only bugs - there's even documented differences)
