SVG Marker gets rendered differently on different screens

Question

Update:

I figured out the screen issue. device pixel ratio is the culprit. On devices with lower window.devicePixelRatio the icon gets displayed smaller, a solution is to make the size of the icon conditional on window.devicePixelRatio, i.e. :

scaledSize: highDevicePixelRatio ? new google.maps.Size(40, 60) : new google.maps.Size(60, 90)

resolution might also play a role, but I couldn't test that as of now.

The issue with Internet Explorer 11 still exists though.

** End Update **

So this is really absurd and I am somewhat still baffled. I noticed this extremely inconsistent behavior of my custom markers. Drove me crazy, because I couldn't figure out why they would be behaving differently. I just now realized it depends on the screen I am displaying the map/marker on. I am using https://github.com/tomchentw/react-google-maps.

I am using a MacBookPro 2015 and a LG 34UC98-W hooked up via HDMI cable.

But not only the screen, also the used browser gives different results. It works somewhat fine on chrome (differences in screens), the marker don't show up at all in IE 11 (haven't tested FireFox).

Now this is how I currently instantiate my marker:

const marker = {
                    position: new google.maps.LatLng(this.state.center.lat,this.state.center.lng),
                    icon: {
                            url: icon_url(this.props.markerIcon,'purple'),
                            anchor: new google.maps.Point(13,42),
                            scaledSize: new google.maps.Size(40, 60)    
                          },
                    draggable: false,
                }

On my MacBook I get the following result: On my LG I get the following result:

This is driving me NUTS, is there a way to achieve consistent behavior across screens/browsers? What is the reason for this???

Following the SVG Code:

I tried with and without the explicit width and height attributes in the first svg tag. Does not make a difference.

Answer 1

I had a similar issue recently and had to change the meta tag in my html to work across devices. Seems like currently you don't have one so maybe try adding the following to your html:

<meta name="viewport" content="width=device-width, initial-scale=1.0,maximum-scale=1.0, user-scalable=0">

If you're only modifying the XML then you may have to use /> to close the tag or use the xml namespace as referenced in this post
