This issue started a couple updates ago for me, at the same time some of my waveforms started not to load on my sequence resulting in a blinking playhead/inability to select any clip while the glitched waveform is on screen. For that I disabled my waveforms whenever I'm not dealing with audio and when I need them I just copy and paste the whole sequence.
Both issues are not a big deal but they're surely annoying since I have to deal with them over and over. Reinstalling Premiere didn't solve anything.
Hey Eduardo - are you still experiencing this problem? I am, and I'm on the latest PPro 14.9.0 on a 2017 iMac Mojave. Drives me crazy that everytime I flatten a multicam clip, I have to disable video keyframes because they've inexplicably been toggled on. Cheers, Patrick
Sadly no, even after many updates and some upgrades on my hardware. The issue also persists while on other machines as well. My current workaround is using a keyboard shortcut to toggle it back (X in my case). Cheers, Eduardo
