**Edit** I can confirm that rolling back my NVidia Drivers to 446.14 has fixed this issue. **
I am having the same problem. This bug started upon installing the latest version of Premiere (14.3) and the latest NVidia drivers (451.48) for my GTX 1070. I've demonstrated it here on a new project:
This is severe and currently I can't edit anything whether old or new projects, they all have the same issue. Like others, I have uninstalled and reinstalled everything mutliple times and tried different drivers.
Also confiming that the glitches are visible on previews and exported video.
Windows 10 64bits - Up-to-date with Windows updates.
Nvidia Studio Driver - v. 451.48
Premiere Pro CC - v. 14.3.0 (Build 38) - English (international)
