> Unfortunately, my experience with the new Metal-driven window server hasn’t been flawless. I’ve run into graphical glitching on both my MacBook Pro and iMac that have persisted into the GM build, and I’ve seen developers on Twitter posting about the same thing. Most of the glitches seem benign (blinking videos, webpages, or 3D graphics), but some seem serious (I can reliably make Finder windows flip out as in the GIF above, and older Nvidia systems have been running into kernel panics throughout the beta process and into the GM). Hopefully, these are issues that can be ironed out in the first couple High Sierra updates and are not ongoing discoveryd-type problems that Apple needs to walk back.
Hence that is why i never liked or trust Graphics Hardware acceleration when you dont have access to the source for Drivers. I really wish Apple would just ship their own GPU in Mac as well, but many people dislike the idea because Apple is unlikely to provide an GPU drivers for Windows, meaning dual booting is no longer an option.
