Drawing thumbail in File Open dialog window - slow to refresh

Hello,

I am testing SW 2016.04 and was wondering if anyone else noticed a slow refresh between thumbnail preview.

The thumbnail lags behind when using the arrow key to switch from one file to another. It takes about 2 sec. for

the next thumbnail to show up.

Anyone have an idea of how to speed this up. In 2013 its instantaneously.

Thanks,

Elmar
