Map grey background on mobile

Hey

I found out that if I press the open button for the map before all page load in mobile then the map load good. (I will notify devs also)

Any idea?

I change to google map and the grey background in mobile problem is fixed.

But I have other problem now, maybe you can help?
I upload map marker icons that their size are 150X150 and I want to resize them to 50X50. I dont want to upload 50X50 icons because then the resolution is terrible. In open street map I did that with css but in google map I could not find how to do it.
I tried with js but it did not work.
Do you have a solution for that maybe?
Is this the direction?
var icon = {
scaledSize: new google.maps.Size(50, 50)
};

Any help will be appreciated.
If I cant change size in google map I would like to change back to open street map and to fix the grey background problem. (but I prefer google map as it look better).

Thanks

Thanks, I will look into it.

About google map and icon size:
using 50px or less icon size look very pixled. in open street map I was able to change icon size and location with css. and it work!
I can change that also in google map but it work different and not good.

Is there an option to add wordpress filter that hook to map initialize and change marker size so it will look good? If you know what is the hook, I will build the function to change the size.
