Hi,
size assistant used for points generates legend size different from map size.
Correct size seems to be the one in the legend

Hi,
easy in fact:

• test a point layer with a fixed symbol size to 24 for instance
• then replace size by an expression set to a constant of 24.

you have a far smaller icon with expression. I guess we have the old scaling area method still applying to any expression output

Hi, I would be very thanksfull if a backport to 2.12 could be done. (christmas is coming...)
We financed this since 2.8 and that feature is ruined without this fix..
