Description

Hi,

Data-defined symbol color is very slow on 2.0 release cause a lot of Qt warnings appears :

QColor::setNamedColor: Unknown color name ’[hex value in database field]’

Setting the symbols color from a database field renders fine but is very, very slow.
No problem in 1.8 release.

Same warnings on labelling

Regards
