After updating (Yes Windows is updated too) I have several malfunctions. The program won't close anymore even clicking the red X. Using camera luts the screen is increased so I have a FullHD part of a 4K footage. It wraps and replaces all kinds of audiofiles in existing projects and unexpected fatal errors occur.
A number of us are encountering real problems with this latest version of VPX, so you are far from being alone! If you read the announcement thread here you will see a number of posts reporting quite severe problems with it.
I think it would be best if ALL similar posts were made to that thread, thus keeping ALL the problems in "one place" so I'm going to request that you copy the content of this post there and, in the meantime, I will close this thread.
