@fclem, is this a known limitation?

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.opengldoes "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.openglare @Jeroen-Bakker, @fclem, is this to be kept alongside the "real" rendering engines?New soft shadows don't support viewport renderto New soft shadows don't support viewport render [no TAA]Added subscriber: @M_Rodionov
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.

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.
