first pic, happens if u minimise css while playing and then maximise again, cant do much about it except live with it and hope someone fixes it
second one, thats the deathbeam, when playing in some server, type deathbeam to enable or disable it, what it does is shows the direction the bullet came from when caused u to die
if u were alive when this happend, probably u died there last time, or if not, some bug with the hack...
