I don't think it has any impact on videos, it's meant to improve the GUI performance - without it the entire GUI would be redrawn at 60fps, with dirty regions only the "dirty" (changed/active?) part of the GUI is redrawn, significantly reducing the workload.
Good point though, as I'd forgotten I still have that in my advancedsettings.xml, and I'm really surprised to see that it's not been added to the system default (on R-Pi).
