In version 23, any type of Multi camera, after starting playback, Premiere "bugs" with the video running. After a few seconds it "unlocks" and applies all commands received in that time.
Even though it's only 2 cameras, with 1/8 resolution without any kind of effect.
In version 22 it worked perfectly with 4 cameras working in 1/1 resolution.
Thanks to Adobe now I can't open the project in version 22.
