Comment 3 Stéphane Guillou (stragu) 2023-11-23 10:44:50 UTC 
Reproduced on macOS:

7.4.6: ~1 second
7.5.4: above 2 seconds
7.6.2: above 2 seconds
24.2 at c60a9db1f2a8e2a088c6b89bcdff4901b28f2864: above 2 seconds

Definitely noticeable now. I'd say the change happened somewhere in 7.5.

Format > Paragraph stays below 2 seconds in all versions tested, no change.

on Linux, not reproduced.

Wondering if it could have a link to the fix for bug 152460, given that I see the same kind of delay for another dialog with font preview, e.g. Styles > Edit Style...

Khaled, what do you think?

No idea, if it is a regression then bibisecting is your best option.

Comment 6 Stéphane Guillou (stragu) 2024-03-19 23:55:15 UTC 
Duplicate bug 160281 suggests it's correlated to the number of fonts installed, so if someone bibisects it, installing some extra fonts might help making the delay more obvious.
Comment 7 sneakers-the-rat 2024-03-22 05:43:51 UTC 
haha yes i knew that having a disgusting quantity of fonts installed would be useful one day. it's definitely `fontd` that's spinning, as the window becomes unresponsive, fontd spikes, and then the window becomes responsive again as soon as fontd relaxes. 

i shall do a bisect another night, can't look at computer anymore tonight <3
