I’m not sure I would call it zoomed in given i’m using the recommended scaling which I’m pretty sure is either a windows default for an HD device or it’s Intel or Nvidia related, all of which are commonly used software/hardware.
I’ve seen this scaling set by default as recommended on more than one HD device and more than one brand of device.
Also if I do zoom in or out the problem can go away depending on percentage selected. For example 10% either way and the problem appears to stop.
I assume Gutenberg editor is default WordPress WYSIWYG and if so I would’ve thought they’d want to fix that. I’ll add a ticket. I think I’ve found the right place to post one.
