--- Comment #8 from Luboš Luňák <l.lunak at collabora.com> ---
Not specific to any drawing backend, I can reproduce with kf5, gtk3, win,
opengl. With some there's no just one line but a grid of them.

It seems it's FillGraphicPrimitive2D::create2DDecomposition() decomposing
bitmap tiling in a way that introduces rounding errors.
