Ugly Line and Border Rendering

Question

I just started diving into WPF. First thing I noticed and which I really hate is the ugly rendering.

I don't know why but for example borders or lines turning ugly sometimes. Take a look at the Screenshot. The bottom line is ugly. Not that crisp like the centered line.

Any suggestions to make that better?

See the second answer of this SO question which suggests using UseLayoutRounding=False in preference to SnapsToDevicePixels.
As an aside if you're using bitmaps then RenderOptions.BitmapScalingMode can be useful (from this SO question

It looks like your lines don't fall on pixel boundaries. Two ways I've used to get around this are:

Use SnapsToDevicePixels. This can cause some noticeably odd spacing if you have lines sufficiently close together.

or

Increase the width of your line so that it full hits a line of pixels. (this has the drawback that the needed width is, again, device dependent).
