SFML cursor left border is broken

[FloweyTF]

I have a sprite for a cursor, and is has a black outline. The left border of it is black, but it shows up as white. I'm on linux.

EDIT: after some more testing, it seem as if there are just random lines on my sprite

Are you using sf::Sprite or sf::Cursor?

For sf::Cursor, note the the warning in the documentation:

On Unix, the pixels are mapped into a monochrome bitmap: pixels with an alpha channel to 0 are transparent, black if the RGB channel are close to zero, and white otherwise.

I'm using sf::Cursor. It states that on UNIX, it behaves like that, but didn't say UNIX like.
