У меня есть динамически сгенерированная карта Google здесь: http://www.socialinvestmentscotland.com/looking-for-investment/case-studies/

Вот javascript сгенерированных карт (в заголовке страницы есть два других массива - simple_markers_descriptions[] и simple_markers_addresses[] - которыеслишком большой, чтобы воспроизвести его здесь): 

var addresses = ["57.1443510,-2.1076268","56.1372861,-3.3121857","55.9645964,-3.1738792","55.8651100,-4.1025119","56.4561225,-2.9863503","56.2444546,-4.2167933","56.9607619,-2.2021569","55.8477464,-4.2950799","58.1476532,-5.2027190","55.9720150,-3.2304094"];

window.onload = initialise;

В Firefox 11 и IE 9 он работает нормально, но в Chrome просто отображается серая рамка.В консоли нет ошибок, и страница успешно проходит проверку.

Я в недоумении относительно проблемы - при разработке страницы я обнаружил, что API Карт Google довольно неприхотливо относится к своему Javascript, нотак как он работает в других браузерах, я опасаюсь слишком много возиться.

В CSS * для проблемы -webkit-backface-visibility установлено значение hidden.Я где-то читал, что это поможет сглаживать края повернутых элементов, но, очевидно, я не проверял его должным образом.

Удаление свойства (поэтому применяется значение по умолчанию, то есть visible),обмануть.
