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.

Do you have the latest version of the macOS driver (version 1.4.0) installed? --> https://www.displaylink.com/downloads/macos

I ask because the release notes --> https://s3.eu-west-1.amazonaws.com/a...ease+Notes.txt

indicate that one of the items improved with this rotation performance:

"C.3 Changes in 1.4.0 release
----------------------------
- Improved rotated-screen performance (32926)"

After updating to 1.4 on BigSur 11.3 i've noticed that I am starting to get times where my vertical screen freezes.

In order to resolve it I have to kill the DisplayLink manager and restart it.
