Bug in face selection?

Greetings, people.

For reasons that I cannot understand, face selection is not working when I activate the “limit selection to visible” button. On the screenshot, I selected the faces forming that rectangle on the middle (using the “C” key mode) but oddly, Blender selects also some random faces out of where I want. It doesn’t happen if I deactivate the “limit selection to visible”.

Am I doing something stupid in here? Thanks in advance!

Never mind. It’s not a Blender bug. Googling a little bit more, I discovered that some antialiasing settings can mess with the Z-buffer, which caused the random selections. As soon as I deactivated it on NVIDIA control panel, it worked nicely again. :slight_smile:
