Scrolling notes does not refresh properly

When scrolling a note either with the scroller on the mouse or using the cursor keys will often produce a partial refresh of the note window (see attached image 1). It happens about 25% of the time and I cannot work out a pattern for it. When I place my cursor into the area it might refresh the whole note, or just a line or part of a line.

In addition sometimes lines appear to be badly rendered. When I place my cursor in the line it will correctly re-render the line (see attached image 2).

Steps to reproduce

Having a note sufficiently long to enable scrolling.
I have found using the scroll-wheel on the mouse the most likely time to generate this issue.
Scroll up or down a few times (it doesn’t have to be far).

Did you follow the troubleshooting guide? Y

I am using the standard release of Obsidian (v1.3.5). I have tested this in sandbox mode, with addons turned off, using default font, using the default theme, turned off css snippets. I have tested it on two windows computers (one 10 Home, other 10 Pro). It behaves the same in all instances.

Expected result

I will get a display like in attached image 1.
Sometimes it will only affect some lines, like in attached image 2.

Actual result

The right hand display of attached image 1.
The right hand display of attached image 2.
