Dialog is not 'moving', allocated width of the drop lists is being adjusted response to content.
Comment 3 V Stuart Foote 2020-05-17 17:05:59 UTC
Also apparent on the Character dialog's Font tab, in addition to Calc's Cell Formatting dialog.

But only occurs for Style listbox for dialog(s) with just a single default Language selection is made (Tools -> Options -> Language Settings -> Languages).

Dialog changes and drop lists are fixed width when font selection for two or more of the Western/Asian/CTL modes are enabled.

@Caolan, is this an effect of welding the font dialogs, would fixed width always be possible?
Comment 4 Caolán McNamara 2020-05-17 18:42:35 UTC
its probably a factor of the contents of the "style" list content changing between fonts so there's a different amount of "extra space" to be divided up between the widgets

that makes the width stable for me
