Blender VSE OpenGL switch is gone in 2.79!

Hey folks,
The only way to get somewhat realtime playback for Blender compositor was VSE Scene strip…There was an option to switch off OpenGL preview to enable compositor preview instead. But in 2.79 it has gone! Have the procedure changed recently? If not then it’s a very bad decision IMHO…:no:
Is there any solution to get it back? Thanks!

I am seeing that rendered option works like previous turn off OpenGL option…
