#1 Original report
The Beam graphic doesn't orient itself like you'd expect it to; looking at them from the side they can barely be seen.

The beams are visible for at the sides and the bottom.
Have to say that they appear thinner when looking from above and the bottom but it's still visible enough in my opinion.
Are you seeing the same? Might be hardware related.

Bug confirmed. It is most visible when perfectly aligned (using C). Also, when perfectly aligned, any beams directly above or below your point of view won't be visible.

they thin out to a line of dots ... or vanish. depending on angle of view
