Sluggish Vertical Display Performance

danhsiu · 06-10-2021, 12:25 AM

I'm using my 2018 15" MBP (Big Sur 11.4) with a D6000 Dell dock to drive two 144hz 1440p monitors. When I turn one vertical, the cursor (and any application present on the vertical screen) feels sluggish over time. Could this be due to a memory leak?

Restarting the displaylink driver helps remove the laggy performance only momentarily on the vertical screen. There is no lagg if I have both screens horizontal.
