Circles used to display point layer in QGIS give strange rendering artefacts - some of them are not round, some have strange shift/repeation. Could this be a Qt bug or QGIS optimisation bug?

QGIS trunk (1.4.0) r12103M

Qt 4.5.3

Gentoo ~AMD64

Still true with a more recent Qt?

Is it still reproduceable?
