[Qgis-user] Issue with How Selected Features are Displayed When Overlapping

[Thayer Young]

 Hi Calvin,
I also agree this is a pain. 
I think the official response to this problem is to right click on the feature in the attribute table and select "Flash Feature" which flashes the feature in red. I usually use transparency when things overlap. If that is not good enough alone, you can combine it with rule based symbology. For example, everything is opaque until something is selected, then only the selected feature is opaque and the rest are for example 30% opaque:
100% opacity rule:  (is_selected() AND num_selected( ) > 0) OR num_selected() = 030% opacity   rule:  not is_selected() AND num_selected( ) > 0
But this won't work if you have different layers that are obscuring each other.
