Have you tried NO sub-pixel hinting (uncheck the box in Control Center and
restart KDE and X)?

This is very odd. A pixel on a digital display consists of one Red one
Green and one Blue element (a set of three) so if it is actually one pixel
wide, then it (if driven with a digital connection) should turn all three
colors off and be black. Only when using the sub-pixel hinting on small
fonts should this happen.
