In the Program Panel. When switching from Fit to 100%, Premiere freezes for nearly 40-50 seconds. It remains on the "Fit" view. It doesn't crash, it just freezes. After 40-50 seconds, the Program Panel now displays the video at 100% and Premiere continues to work.
I'm trying this on my system on Premiere Pro Beta 14.2 build 11 and I'm not seeing this happen. Could you let us know which build and version of Premiere Pro you're using, and also basic system specs like Operating System, CPU, GPU, and RAM? Thanks!
