Midi Notes will not stay on grid in this new update

I am getting so frustrated with Steinberg and all the quirks we get and now to top it all when trying to edit midi notes and put them where i want them they move the next time i play back.
I put notes just slightly forward on a bright song and when replaying some notes or the grid has moved and it can be as much as a sixteenth or just a little more .
Is this a bug in the 41 update ??

all the Best John

Please see this topic for a workaround:

If you’re on Mac, you can just disable GPU acceleration.

This should be fixed very soon.
