[Reg] QPalette:setColor white always draws black

Updated from 6.0 to 6.3 and noticed that the text colour was not white anymore.

QPalette::setColor(QPalette::Text, Qt::white);
QPalette::setColor(QPalette::Text, QColor(255, 255, 255));

These will both result in the text rendering black

setColor(QPalette::Text, QColor(255, 254, 255));

This will result in the text being drawn white (well almost, 254 instead of 255 )
