Can confirm.

Hm, if I have a look with --debug-depsgraph, then I can see something like

[RENDER]: BKE_animsys_eval_driver on OBGrass.006 (0x7f8ebd42b608) fcu scale[0] (0x7f8ed2a19088)
[RENDER]: BKE_animsys_eval_driver on OBGrass.008 (0x7f8ebd42c208) fcu scale[2] (0x7f8ed02a1b08)
[RENDER]: BKE_animsys_eval_driver on OBGrass.006 (0x7f8ebd42b608) fcu scale[1] (0x7f8ed2a19108)

for every frame...

not sure what is going on [would need a deeper look], maybe @Alexander Gavrilov (angavrilov) has an idea right away?
