When a layer symbol is defined with map units or "meters at scale" unit, it is sometimes shown in the legend at a very small scale, preventing to see the details. Or if we zoom in the map, the legend will be shown in a very large scale, see image below (reference https://issues.qgis.org/issues/8884 )
Is there a way I can keep the layer symbol scalable in the map, but have fixed size for the layer symbol legend?
