As for the second case, for Adjustment layers there is a "Composite Copy"
option in the Layers docker. And the last time i tried, it used to work.
Doesn't it?
By default all the layers (and masks) use Composite Over mode, so you see
this effect. And it also mean that direct application of the filter will
always be in Composite Over mode. This is a lack in the ui, i guess.

As for the first case i should check it.
