Can you do a screen record showing the issue?
Unfortunately not Mike, as I don't have the authorisation to show it to public as of yet. If you can imagine it's more to do with the after effects file that is causing the glitch. I have also tried reversing the update but it is still glitching and blinking red at times.
Have you resolved the issue? We need more details to understand the issue. It will be helpful if you share a screenshot of the issue with some sample footage.
Also, share the system specs(OS, RAM, GPU, CPU) with us. Have you updated the GPU drivers?
