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.

Did you read my last comment ? Only AMD Navi GPUs (RX 5000 series) seem have this problem. So your Radeon Pro 5700 XT is what? Big Navi card? or just another Navi card?

Thanks.

I've reset the SMC and NVRAM (saw 2 apple logos, I'm 16" MBP). Issue still exists.

Safe mode does not let you connect more than 1 external display nor does it let you rotate external displays.

I'm using a magic trackpad. Issue exists wired (lightning -> usbc cable) or bluetooth.

Running into the same issue with my MBP 16" in the exact same spot. The mouse disappears, shifts, and is inaccurate on the right inch of the screen by about 50 pixels, only when at 90°. Did you ever find a solution?

Aug 17, 2020 8:53 AM in response to Steven__K

Bah, ignore my previous post, this didn't fix the issue, just moved it. The mouse "worm hole" still exists in this orientation, but it is seen at the bottom of the display instead of on the right side. :(

BTW, I have another problem with my external display configuration ... I have the MBPRO 16" & 2 identical 28" Samsung external displays. 1 external display is horizontal & other other is vertical. Often when I reboot, 1 or both external monitors have their orientation setting changed, resulting in vertical display shown on horizontal monitor, etc. Changing the values back fixes the problem (until next time); but doing this is very difficult since cursor movement is based upon a different orientation than the monitor orientation! Furthermore, the System Preferences window & its Displays window often are shown on the wrong monitors. When it's expecting a confirmation of the latest change, it expects a click on the appropriate button in an appropriate window. But it usually takes longer than the allowed time to get the cursor there!

Does anybody else have this problem? Any suggestions, workarounds, etc.? Any easy way to reset the orientation settings using a script or similar approach?

Thanks!

APPLE WHEN WILL YOU FIX THIS! Its driving me crazy. I didnt spend all this money on a laptop and monitor just so that I cant click anything on the right edge of my screen (do you know how hard it was to get to the second page of this support ticket???)

Nov 9, 2020 11:04 AM in response to rynop2000

looks like a rounding error somewhere :) some mismatch between the scaling and rotation, its a shame Apple don't seem interesting in trying to fix it. I tried to explain it to the phone support and they just kept asking me to reset my computer, as if thats going to fix their bug and didn't seem to have any way for them to escalate it to a person who can fix real problems

That is ridiculous. I already went through all that rigamarole so others would not have to.

I've just sent a note to the support rep associated with my case.

Does anyone know if posting a support case number on the discussion forums is against the TOC? If its not, I can post my # so when others call they can reference it and not have to jump through all the hoops.

Ah, that's terrible news - sounds like Big Sur isn't going to fix it.

FWIW, I also noticed that when screen sharing in Zoom, the person watching the screen doesn't see the glitch; it only shows up locally on my monitor but not to people watching the screenshare.

Something definitely weird going on.

****, Bro I think we should give up with Apple support because as As I mentioned earlier (another comment), I already with Big sur updated (fresh installed) but this problem still appear. NOTHING FIXED and Big sur have event more bug than Catalina when it was launched so stick with Catalina until macOS v11.4 or more release. Very disappointed with Apple Dev teams

Yup did see that. While I'm super disappointed in Apple, I'm not going to give up quite yet. Me being able to confirm Big Sur does not fix the issue, will allow me to re-engage Apple engineering - the only people that can really get this super super annoying/productivity killing bug to go away.

I spoke too soon. Big Sur upgrade fixed one problem but created another.

The pointer location and the click location are no longer off for me on my 270 degree rotated monitor (one to the left of my iMac display). The pointer and click location discrepancy has now moved to the bottom of the screen. My mouse completely disappears towards the bottom, and when it reappears below, the pointer and the click location are off.

I have another vertical monitor on the right side of my iMac, that is rotated 90 degrees. It exhibits the same mouse disappearance then location/click discrepancy - but on the right side of the monitor.

Video showing the problem is below:

OP here. Sorry, I forgot to mention I called Apple ~10 days ago updating them on the continuation of this bug.

Senior support and Engineering is now aware that Big Sur not only didn't fix the issue, but now it manifests itself in a new way.

I have passed this video along to Apple engineering: https://youtu.be/4G2ip075tqs

I'll post another update when I hear back.

Dec 23, 2020 5:36 PM in response to rynop2000

Lol, I just "accident" find it out.

After 10 hours of work, I leave my workspace and take a rest.

After comeback, I realize this "buggy" issue disappeared, so I'm think maybe...

Then I try to simulate what I did before I'm leave my mac and BOOM you know the rest.

Omg , now I can sleep in peace - Finally.

The bug came back after waking up my computer this am. I have the "Active screen corners" setup just like you do. It worked yesterday after following your instructions and putting to sleep via hot corner, but logging in after overnight and it came back :(
