Weird grid resolution in the keyeditor (dorico 4.1)

I’ve noticed gaps and random spaces using grid resolution in write and play mode
Is it just me or it is a common bug?

It’s a display artefact, caused by the fact that the grid lines in the Key Editor are drawn with a thin pen that can be drawn at less than one pixel’s width on a low pixel density display. When a pen is thinner than a pixel, if it falls between two pixel boundaries, it may either be drawn as an anti-aliased line across two pixels, or it may not be drawn at all.

We know this doesn’t always look good on low pixel density displays and we are thinking about ways of improving it for low pixel density displays without making it look significantly worse on higher pixel density displays.
