Apologies if this has already been addressed. I have been using an older version OpenLP reliably using an old Macbook Pro but avoiding video totally. I recently got a used 2019 macbook pro i7 with a fresh install of 15.5. The latest version of OpenLP plays videos great on this machine but using motion video loops gives me a quick flash at the loop point. Is there a setting somewhere in the OS or the program that might fix this? Thanks in advance!
