As a workaround pressing the "1:1" button gets the diagram to show at 100% zoom.

Please update and report back if it happens again. Thanks

[craigwardman]

yes it seems to have fixed the zoom issue. Not sure if it's related but with "SVG preview" enabled none of the sprites work, just get a red box with a cross through it. Disabling "SVG preview" fixes it.

[krasa]

Yes, SVG rendering of sprites is now broken.

[krasa]

Fixed.
