Hello Tim, thanks for your quick answer. There is another issue with regular masks that don't show up (full white screen) in the playback preview, but they do in the rendering.
When? Where? There's not enough in this post to have any idea what you are doing when a mask does not show up. It could be related to ray-traced rendering, track mattes, mask modes, all kinds of things. Details please.
Since 188.8.131.52, basic masks (for example font+regular mask apparition) bug in the playback. On the duration of the whole masked layer, a white screen shows up during playback and makes every change impossible. The project was built on 12.1.
System and comp settings:
3.5 GHz Intel Core i7
32 Go 1600 MHz DDR3
NVIDIA GeForce GTX 780M 4096 Mo
I am not seeing this on any of my Mac's but I'm running OSX 10.9.1
