Video display issues using OpenCL in 2019 update

After updating to 2019 and attempting to work on a project I was using in the previous version of Premiere, I am encountering a number of issues with the display of the video.

I am on Windows 10, using Premiere Pro v13.0 Build 225

When I set the Renderer to Open CL, I experience this:

• Some clips show in the program viewer with a green glitchy overlay.
• Some clips do not how in the program viewer (just shows blackness)
• If I turn the Proxies off, the clips appear (but some clips stil have green glitch overlay). Playback is extremely poor.

When I set the Renderer to Software Only, the odd green glitches do not show.

When I open the project in the previous version of Premiere (12.1.2) I am able to use the program as expected. I will continue to use the previous version of Premiere for now, but I would like to troubleshoot this issue so that I can use the new version of Premiere.

Thank you.
