[OT] Slow performance under Yosemite

[Roger Guay]

Mike,

I am still trying to figure out why I get random screen flashes in all recent versions of LC since I upgraded to Yosemite. I seem to be the only one having this problem so it shouldn’t be of great concern to you. (BTW, these flashes occur randomly when using lock/unlock screen with visual effect.) Other than that, I’ve had no problems with Yosemite on my MacBook Pro Retina.

Cheers,
Roger
