I have seen this with Photini on Windows, where PyQt version 4.9.6 is installed. I have not seen it on my Linux computer which uses PyQt version 4.10.3. I don't know what other versions may be affected.
At present the only workaround is to use one of Photini's other map tabs.
There is a recent bug in the Google maps API that affects some browsers. (See https://code.google.com/p/gmaps-api-issues/issues/detail?id=7475)
