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 @angavrilov has an idea right away?

@hazukiaoi Currently the blend file contains 76 objects, many of which are animated. Please take some time to strip the blend file of everything that's not necessary to demonstrate this issue. If it can be shown with just one object, that would make debugging things much easier.
