I suggest we fix this bug on by either of the two options below-
- Option 1 : Recreating the CVDisplaylink on screen sleep/wake events
- Option 2 : As noted by you as a JBS comment - `Actually, the simple hack to resolve this particular issue is to replace this call with CVDisplayLinkCreateWithCGDisplay(CGMainDisplayID(), &displayLink)`

I have implemented and tested Option 1. I have not tried Option 2 yet.


The code refactoring that you have done can be done as a separate JBS issue if needed in future. What do you think?
