On a 5,1 I have three cards: 1080ti in the bottom slot, 1080ti in the next usable slot up (2?), then an m4000 in one of the top two slots.
If I plug my screen into any card/port other than the 1080ti in slot 2, the macOS gui is glitchy/ghosting/slow/not correct. I'm using display port cables.
Why might this be?
Driver 387.10.10.10.40.105
...updated to 17G6030, 387.10.10.10.40.127, no change
...downgraded to 378 per this thread and all ports are fine (https://forums.macrumors.com/threads/mac-pro-5-1-3x-gpus-running-slow.2180558/)
