 WMS layers often/somtetimes do not display when render cache is enabled
 and there are several vector layers (Postgis in my case) rendered on top
 of the WMS.

 Display works reliable if render cache is disabled.

 The problem seems to get worse if more vector layers (or layers in
 general) are involved.
