Растровый слой OpenLayers-3 не отображается, когда Chrome развернут в оконном режиме

У меня есть эта странная проблема с OpenLayers 3, отображающим слой Mapserver WMS.

Когда Chrome находится в развернутом режиме, сетка не отображается. Однако, когда я переключаюсь на вид «окно» или как там это называется, все работает безупречно.

показывает сетки
сетка не отображается

EDIT Я только что обнаружил, что mapserver записывает в файл журнала следующую ошибку: [Mon Apr 11 15:08:46 2016].291000 msWMSLoadGetMapParams(): ошибка сервера WMS. Размер изображения вне допустимого диапазона, WIDTH и HEIGHT должны быть между 1 и 2048 пикселями. Очевидно, увеличение размера окна также приводит к тому, что WMS создает больший png? Как мне решить эту проблему?/EDIT

Вот код Javascript:

            rainfall: 500
        });

        farmerFeature = new ol.Feature({
