my (cut down) code is as below. My markers are not showing up until I either click or move the map slightly... is there any way of getting around this so they show up instantly?

It seems that the problem is still exists in google chrome in most recent version on google map api and marker cluster js.
So I'll post the code which helped in this issue for me.
google.maps.event.addListener(map, 'zoom_changed', function() {
setTimeout(function() {
var cnt = map.getCenter();
cnt.e+=0.000001;
map.panTo(cnt);
cnt.e-=0.000001;
map.panTo(cnt);
},400);
});
feel free to play with value of interval of 400 (in my case less than 400 woudn't fix problem, but higher value - higher lag time)
P.S. make sure you have defined map variable:
map = new google.maps.Map(document.getElementById("map-canvas"), mapOptions);
I was struggling with the EXACTLY same problem and was so glad to hear other guys have the same problem. I experienced the problem with GMaps V3 in Safari and Firefox as well. I tried your solution and it works for me as well but I used the idle event instead the timeout:
google.maps.event.addListener(map, 'idle', function(event) {
var cnt = map.getCenter();
cnt.e+=0.000001;
map.panTo(cnt);
cnt.e-=0.000001;
map.panTo(cnt);
});
Just add it on initializing Google Maps. There might come up another issue working with infowindows and circles bound to markers. In my case I can set the radius of the circle in the infobox. Jumping out of the input field (with or without changing the radius value) makes red-like markers blue. If you then zoom in/out the original color reappears. To solve this problem you have to change the zoom level quickly (in radius_changed event):
map.setZoom(map.getZoom()-1);
map.setZoom(map.getZoom()+1);
