- Sanitize framebuffer. Original idea from @StevenMattera - Change clear framebuffer to memset (for grey colors), for performance (we don't use alpha blending, so it does not matter to set it to 0xFF). - Enable screen backlight after gfx init - Reduce wait time for emmc/sd read/write retries to 100ms.
