Mac black screen when jumping into 1DQ

I jumped into 1DQ from T5Z 3 times today. Each time my Mac ended up black screening. Could still hear sounds but the screen didn’t ever come back. Needless to say, died each time (twice to a solo tengu sniper - oh the shame).
I heard another player in Horde report the same thing last night, saying it might be down to the bubbles on the gate (the irony is not lost on me). Anyone else seen anything similar?
