macOS 10.15.5 broke mouse pointer location on vertical display

I have an external display that I rotate 90 degrees so it sits vertical. Ever since upgrading to macOS 10.15.5, when my mouse gets close to the edge of the screen, the pointer location gets shifted.

The best way I can explain it is with a screenshot.

My mouse is where the red arrow is, and you can see the x in the tab is highlighted (x to the left of "New tab"). The OS thinks the mouse is hovering over the x, however my mouse is ~50 pixels to the left.

Any ideas? I've tried:

restarting
changing the scaled resolution of the vertical display
rotating display back to normal (no rotation, aka "Standard"). In this orientation I do not have the issue

MacBook Pro 16″, macOS 10.15

I found another workaround:

After re-connecting the cables, I changed the display "Rotation" setting in Sys. Prefs from 90º to 270º (and physically rotated the monitor 180º to match the display's visual rotation) and this has eliminated the mouse "worm hole" issue.

It would be great if this issue could be fixed though.

Thanks for opening this issue in the first place. Unfortunately this Solved mark is misleading and doesn't work for me at all. I also have vertical monitor and this cursor jumping at the bottom of the screen is driving me crazy.

Yes, It 's just temporary fix.

But as I tested on at least 6 MBP and iMac, my temporary solution work in all device.

So make sure you follow every step in my fix guide.

I'm doing it every day and have none of issue at all.

Hi @Luv4ever1105, this doesn't work for me unless I am misunderstanding your instructions. I use mac in clamshell mode with 2 external Dell monitors rotated vertically. Let's call them monitor 1 (main) and monitor 2. The dead zone is the upper right corner of monitor 1. I turn off monitor 2, and put display to sleep in monitor 1. I turn on monitor 2. But the issue is still there. Further, do you have to unset put display to sleep after you set it?

Thanks for your help.

Thanks.

I created a new account and still experience the issue when logged into the new account.

Issue occurs regardless of resolution setting, on this monitor that is rotated 90 degrees.

I was hoping macOS 10.15.6 would potentially solve this issue, but it does NOT.

I'm dreading the painful process of going through Apple Support but I guess I'll take the plunge again.

Same issue here. Happened around the same time as 10.15.5 and was not fixed in 10.15.6. Using a Dell P2715Q display rotated 90 degrees. I'm also using a Belkin dock. Is anyone else using a dock?

Sep 15, 2020 11:47 AM in response to brenan-chillah

I was using a dock originally, then tried another dock, and finally switched to a direct USB-c to HDMI cable and it still doesn't work. The problem isn't your dock.

I have the same problem with my MBPRO 16", except it's based upon vertical position at the bottom of the vertical window, not horizontal position.

> Really?

Yup. I honestly didn't expect it to be fixed. I didn't reset NVRAM or anything.

I have this issue as well and it makes using using a 4k monitor at 90 degree resolution useless for me. this is an embarrassing bug for a trillion dollar company.

WOW - this worked. Fixed both my external displays.

How did you even think to try this as a fix?

Thank you thank you!! Merry Christmas!

Anyone know how I "undo" marking this question as solved? The current reply I marked as solved, is just a very temporary fix.
