mapbox blurry popup
// Fix blurry mapbox popups due to transforms on non-even height & width element
// 1. Add class to popup when set with marker
new mapboxgl.Marker()
.setLngLat([obj.lng,obj.lat])
.setPopup(new mapboxgl.Popup({
offset: 25, maxWidth: '240px', className: 'makeMeEven'
})
.setHTML(html)
.addTo(map);
// 2. Using JQuery to make height & width even on map's mouseup event
map.on('mouseup', function(e) {
setTimeout(function(){ // Slight delay to allow popup to be added to DOM
$(".makeMeEven").each(function(){
$(this).width(Math.round($(this).width()/2)*2);
$(this).height(Math.round($(this).height()/2)*2);
});
}, 1);
});
