Zoom Drag does not follow mouse cursor properly

I just installed Cubase 10 & the zoom drag behavior in the main project window does not behave as it normally should.

The mouse cursor will drift farther and farther away from the playhead randomly as I’m attempting to navigate around the project window using the zoom/drag up and down feature (ie. dragging down from the marker track and then moving left and right with the mouse to scroll).

Also I’ve had the waveforms and MIDI notes completely go blank when I drag/zoom like this as well, although this only happens at random thus far.

this issue is there since ver. 7, I reported it several times, and as you see, no fix.
My workaround is to disable Zoom Drag thing
they will never fix this.
