if you play bubble shooter instead of hidden object it seems to work ok in the main chapter (except for the odd ball that comes out a different colour than shown in the shooter). In the bonus chapter it doesn't seem to recognize when you have gotten everything, it stops making the noise that normally indicates that you removed an object from the list and just keeps going and going. If you click the button to switch back to hidden object it will remove all the objects and finish - but you shouldn't have to...

Apparently, having GTX1060 & i3-8100 & DDR4 2400mhz 8Gb is not enough for this game. I'm kidding, it's more than enough, but most likely a problem with the game unable to recognize the new-gen hardware. Care to fix it? So far, I just edited options.cfg, then set it to read-only....
