Same issue Targus Dock180USZ-50
MacBoook Pro 13" 2019 Four Thunderbolt 3 ports, 2.8GHz Intel Core i7 CPU, 16GB 2133MHz RAM, Iris Plus Graphics 655. OS X 10.14.6
2x Dell U2717D 27" 2560x1440 Monitors 1x Portrait.

I know it's the OS X DisplayLink driver (currently using "5.2.4" (shows 5.2.82)) because when I plug in my Dell XPS 13" Windows 10 Pro to the same exact setup I have no issues.

Same rotated screen huge lag: MBP 13-inch, 2019, Four Thunderbolt 3 ports, 2 displays Dell U2715H linked to an i-tec 2x4k docking station with power delivery

I have the same problem lag on a rotated screen! Is this going to be fixed?

Rotation should work on mac, it works for windows well!

The drivers are unusable on Mac with a rotated display. It seems this bug has been ongoing for 4+ years, is there any ETA on a fix?

Issue still happening. Please resolve this so we can continue to use this product! Would hate to have to switch over to a new brand as this one has all the connections I need. Catalina 10.15.4. Horizontal is smooth but soon as I switch to a vertical view, issue happens. Works with Bootcamp just fine.

I Use Ubuntu GNU/Linux for business and pleasure and I have no issues when I use the display horizontal (1920x1080 for watching movies) but as soon as I rotate it 90 deg to the left right or to the left (1080x1920 for coding, PDFs, and browsing forums) It lags. but is fine with my PDF reader and some of my IDEs. I'm assuming based on my experience its fine with applications that are mostly white like Code::Blocks and Okular. Hey DisplayLink devs, MacOS and Linux users are just as important and should get the same treatment Windows customers do when it comes to drivers, functionality, stability, and support. If your going to be slow about it just be cool and open source your drivers so the community can help!

Still having this issue.

Asus ZenScreen Go, macOS Catalina, DisplayLink USB Graphics Software for macOS ver 5.2.1.

I'm having this issue as well!

Some how, FPS or refresh rate on my rotated external monitor (connected via USB-C dock through DisplayPort) is much slower than on the regular screen.

I am using masOS 10.15.3 with the latest DisplayPort driver as of 12. march 2020.

Please investigate this and fix.

Can't roate external screens in "macOS Catalina v10.15.3"

Please fix this!!!!!

Catalina, cannot rotate screen... Would really appreciate it if this can be fixed asap... Thank you!

The new update (DisplayLink macOS App PREVIEW - Alpha) completely remove the ability to rotate your screen, please don't install as you will lose the ability to rotate the screens. Hope the full release will allow this feature.

Having the same issues previously on Mojave and now on Catalina 10.15.2 with the Targus Dock180

Same here. Setup: MBP16 with Targus DOCK190EUZ.

Confirming as of December 16 2019 The issue of extreme lag on rotated monitors using DisplayLink with MacOS still exists. DisplayLink USB Graphics Software for macOS 5.2.1 has not been updated, and there has not been any remedy provided.

To add to the pile, this is a huge annoyance for me as well. I spent a considerable amount of money on a dock for my updated MBP and one of my monitors is rendered near useless as a result. I see that this is "started" so I'm hopeful.
