Mac Champ Select Glitch??

Please get rid of this glitch I am begging of you.. I have been experiencing this glitch for around 2 months now where in a few games (at random) in the new client during champ select I would not be able to see or select any champions. This eventually leads me to have to dodge due to not selecting anything on time. This even made me lose my promos as well as wasting a lot of time in lpq... Fix this please!!!!
