Mercury Playback Engine GPU renderer causes exported video to have green frames. Used to work fine.
Windows 10
Premiere Pro CC 12.1.1
I can no longer export video when using the renderer in my project set to "Mercury Playback Engine GPU Acceleration (Open CL)" without the exported video file exhibiting flashing green frames when played. The video plays fine in Premiere with the renderer set to this, it's just when I export that it's a problem.
I used to be able to export using this renderer and the video was fine.
I have not changed any hardware on my system. The only things that I can think of that have changed are the version of Premiere (although I've tried uninstalling it and going back to older versions but that did not fix the issue) and I think Windows 10 installed the latest version of itself.
Exporting using "Mercury Playback Engine Software Only" works fine but I'd rather use the GPU option as it's faster and used to work fine.
