#3694 new bug
WMS quality worse on QGIS server compared to QGIS desktop

Description
Since a couple days/weeks it seems like the display quality of WMS, when used through QGIS server got substantially worse.
It could be either a dpi, or a resampling issue, or an unnecessary reprojection which results in lower quality.
Here is a test URL: Original UMN Mapserver URL with original quality: http://gis.uster.ch/cgi/mapserv?map=/home/www/mapserverdata/uster_uep.map WMS through QGIS server: http://gis.uster.ch/cgi/qgis_mapserv.fcgi?map=/home/www/projekte/orthofotos_und_uep/orthofotos_und_uep.qgs Layer: Übersichtsplan 2009

The DPI bug was fixed in trunk r15699. Can you verify if this ticket was also fixed?

Here is a Screenshot: on the left is the better quality of QGIS desktop, on the right the lower quality of QGIS server. Both use the same WMS from UMN mapserver as a source.
