Hi, I'm using Camtasia 2018.0.0 (Build 3358). I'm facing too many problems. (1) My display starts blinking when I start Camtasia and also blink during production. I didn't face this problem in Camtasia 9. (2) When a do a sharp cut to a audio, Camtasia fails to pronounce at the very beginning of the audio and after producing the video that problem stays remain. (3) When I produce with custom production and choose to produce only audio, it produces all audio in timeline although I turned off other audios using eye button from the bottom left corner.
