@Clément Foucault (fclem), is this a known limitation?

(Edited: I confused viewport render with view render F11)

Hm, pretty sure this is more or less working as intended.

Temporal AA [Viewport Samples] only kicks in for doing "real" eevee engine rendering (eevee_draw_background).
Since the bpy.ops.render.opengl does "only" ED_view3d_draw_offscreen, there is only one sample in effect so to say.

Not sure what the future plans for bpy.ops.render.opengl are @Jeroen Bakker (jbakker), @Clément Foucault (fclem), is this to be kept alongside the "real" rendering engines?

Viewport rendering should do a "real" eevee rendering but without re-exporting scene every frame like it does now. This could be a game changer like it was in 2.80 alpha. With this "real" viewport rendering eevee renderspeed is comparable to twinmotion renderspeed and to lumion renderspeed. So viewport rendering needs AA back...

Yes, if this is the case, than it is an actual issue. Can check tomorrow what is going on.

Jeroen Bakker (jbakker) claimed this task.

It seems that multiple samples are calculated (you can see this by adding a volume object to the scene) the volume object is rendered with multiple samples.
Will check if the soft shadow light location and buffers are recalculated.

"Sun" softshadows are "soft", only other lights are sharp - point, area, spot
