Found a fix,
#buddypress a.button {
background: -webkit-gradient( linear, left top, left bottom, color-stop(.2, #f43b32), color-stop(1, #d2231a) ) !important;
background: -moz-linear-gradient( center top, #f43b32 20%, #d2231a 100% ) !important;
-webkit-box-shadow: inset 0 1px 0 hsla(0,100%,100%,.3) /*Top*/, inset 0 0 2px hsla(0,100%,100%,.3) /*Shine*/, 0 1px 2px hsla(0, 0%, 0%, .29);
-moz-box-shadow: inset 0 1px 0 hsla(0,100%,100%,.3) /*Top*/, inset 0 0 2px hsla(0,100%,100%,.3) /*Shine*/, 0 1px 2px hsla(0, 0%, 0%, .29);
}
seems to have removed the gradient for me.
