This reverts commit f081cd4ca2658752a8c0e2353d50aec80d07c65f. Some users have reported flickerng with S/G display. We've tried extensively to reproduce and debug the issue on a wide variety of platform configurations (DRAM bandwidth, etc.) and a variety of monitors, but so far have not been able to. We disabled S/G display on a number of platforms to address this but that leads to failure to pin framebuffers errors and blank displays when there is memory pressure or no displays at all on systems with limited carveout (e.g., Chromebooks). We have a parameter to disable this as a debugging option as a way for users to disable this, depending on their use case, and for us to help debug this further. Having this enabled seems like the lesser of to evils.
