Strange Looking Column Selection

[Arthur]

If I work in column selection mode I get selections like in the picture. Is that normal?

[alex]

Yes, if you used non-monospaced font.

[Arthur]

It is monospaced - Anonymous is the name.

Arthur, I have doubts that it is really monospaced. Definitely some symbols have different width (fex space and W).
Try with Courier New, if you would get same display, it is a bug.
