The video performance of the X1 Yoga is horrible. Connected to the OneLink+ dock, and driving two external monitors as well as the X1 screen, edits made in Microsoft Excel take 5 to 10 seconds to roll across spreadsheets, even on relatively small (5MB) workbooks. Additionally, video resolution on external monnitors doesn't support the default resolution for them. Instead, resolution is lower, making everything larger than needed.
Are these knoiwn video driver issues? Is a fix in the works?

I use the X1 Yoga with two external displays (1920x1200), and have no problems whatsoever.
Do you try to use 4K displays by any chance? Running 2x 4K displays plus the Yoga's own screen is not possible at the same time, even with the OneLink+ (as far as I know), which could explain why you get lower than native resolution.
As for the performance problem in Excel, I cannot really explain it. Is it just a display issue? If you disconnect your notebook from the OneLink+ dock and do the same thing on the notebook screen, does it still lag, or does it work better?

Neither of the external displays is 4K. They're daisy-chained through one of the DisplayPorts on the dock. Looking at tech specs on Lenovo site, it looks like I shouldn't daisy-chain them. May get better resolution if each is connected directly

Changing the displayport connections did nothing to improve video performance. It is still poor, with long lags between file edits and their visibility on screen even on relatively small files.

Could you check if the data update delay exists if you use the notebook disconnected from external displays, and viewing the data on the display of the notebook itself?

Another issue arose today, when a notification popped up that the video drive stopped working. The screen never flickered and never wnet dark, but the notice popped and then disappeared.

The Intel driver crashes happen sometimes, it is not just an issue with Lenovo or ThinkPads. Luckily in Windows 10 it can recover from these, although it is annoying when it happens.
As for the blackening screen, hopefully Lenovo can investigate your issue further, if the driver, firmware and BIOS update did not solve your problem.
