When I move my mouse off of one screen and onto another, sometimes (roughly once in five attempts, I'd say) the mouse will jump to a seemingly random edge of a monitor. The mouse may jump onto a different monitor, or it may wrap around to the opposite edge of the monitor I just tried to move my mouse off of.
Here's a rough diagram that I hope helps illustrate the behavior:

(edit: the image isn't appearing for me, so I included it as an attachment as well)
The behavior can happen when moving the mouse off of any of the monitors, and it happens even when I have some of the monitors disabled (for unrelated reasons).

I found this old thread that appears to be describing the same behavior I'm encountering:
https://www.displayfusion.com/Discussions/View/mouse-wrap-not-working-consistently-after-updates/?ID=fe246736-0bb8-4585-83e3-2baf6dd4a967

I'm using DisplayFusion Pro on Steam 10.0, when I click Check for Updates Now it says I'm on the newest version.
I am using Windows 11, but this behavior was happening consistently while I was on Windows 10 as well. This behavior has been occuring for as long as I've had Display Fusion, for at least one or two years, but I don't know exactly how long it's been.

I've attached debug info for two occasions where I was able to reproduce the behavior. For both of the logs, I cleared the logs immediately before reproducing the behavior, so each file only contains 10 seconds or less of logs - hopefully that makes it easier for you to comb through them.
One of the logs was done on "Log Minimal", and the other was done with "Log Detailed", but I don't remember which is which.

It looks like DisplayFusion thinks it's moving to the correct location every time. Could you send me over a video of the issue?

Here's a recording I was able to get, along with a debug file I made during the recording.

I was able to reproduce it on the two outside edges of my monitors, but not on the inner borders between monitors. I know I've experienced it on the inner borders before (for example when moving from one landscape monitor to the other), but unfortunately I wasn't able to make it happen for the recording.

I'm using the PowerToys Find My Mouse utility to highlight my cursor in the recording.

Thanks for sending that over, I was able to reproduce this on my end so I've added it to our list to look into.

Thanks!

I've had this issue for while now, too. Sometimes I can't even "escape" one of my monitors because the mouse keeps wrapping around it instead of moving to the next one.
Most of the time I just ignore it because it doesn't happen that often but sometimes it happens almost every time I move the cursor to another screen. It can get almost comically bad when I, for example, try to move the cursor from my left monitor to the right by moving it over the right edge of my left monitor, it jumps to the left edge of my left monitor which can cause me to "search" for the cursor as I expected it to appear on the left edge of my right monitor. This causes me to move the cursor so I can find it which sometimes causes me to accidentally move it over, in this example, the left edge again and then I look to the right because I expect the cursor to appear on the right monitor at the right edge this time...but no, it appears on the left edge of the right monitor xD this can lead to some kind of hide and seek with the cursor :-[

I found another tool on GitHub which does seem to do a better job at mouse wrapping, perhaps you can take a look at how they do it and improve the current implementation in DF?
