When I export a movie from Final Cut Pro to compressor, it begins running just fine. However, it will eventually cause my Mac mini (2018) to start getting graphical glitches (parts of the window or dock will flicker in and out) and eventually the computer will lock up, then shut down. I have 32GB of RAM, of which only 16GB are used, so I don't think it's running out of RAM. I've ran Apple Diagnostics numerous times and it doesn't detect it, nor do I have issues with anything else graphically intensive. My CPU doesn't go above 150℉ [65℃], and the GPU doesn't go above 180℉ [82 ℃].
Does anyone know what might be causing this? I'm getting tired of losing progress on projects (apparently final cut doesn't immediately save) as well as the additional time it takes to render something many times before it actually succeeds.
This has started happening while rendering the video (inside Final Cut Pro). Does anyone have any idea what's going on?
