Reversing speed of clip causing playback and render issues.

[PaperFortress]

Everything is functioning smoothly while editing, however every time I reverse the speed of a clip playing it back freezes playback (audio still runs but video stops completely) and takes about 10x the amount of time to render that clip compared to any other clip/effect.

Any thoughts on what could be causing this?

Setup: 2015 MBP, 16GB, new Lacie USB 3.0 external drive/cable (I know, dont yell at me) and Premiere is up to date.

If that doesn't work, try resetting the Workspaces:

Reset the current workspace to return to its original, saved layout of panels.
1. Do one of the following:
• Click the Workspace menu icon and select Reset to Saved Layout.
• Choose Window > Workspace > Reset to Saved Layout.

If that doesn't work, try Preferences > Audio Hardware and set Input to None.

If that doesn’t work, try updating or rolling back your graphics driver directly from the video card manufacturer’s site. If NVIDIA, do a clean install of the latest Studio Driver (NOT the Game Driver)

If that doesn't work, try creating a new project and import the old one into it.
