Mouse often in wrong place

[WalkerJ]

This issue happens to me when I use NoMachine in full screen, which puts it in another desktop “space” on current Mac operating systems. Sometimes switching from the NoMachine desktop space to my primary space and back will trigger it, but not always. If it happens the only way I’ve been able to fix it is to close and reopen NoMachine, but that doesn’t always work.

Another issue that also happens when using NoMachine full screen is that sometimes the Mac menu bar is still present and overlaps the NoMachine view. This is a problem because the Macos menu bar covers the top of windows and prevents moving the window or something accessing menu options. I don’t know if these two issues are related, but they both happen under the same circumstances for me, so maybe using full screen is a trigger for one or both?

I attached a screenshot showing the Mac menu bar overlapping the NoMachine window in full screen.

Hi, regarding the menu bar issue, we are working on improving the user experience when using NoMachine in fullscreen on macOS, and these improvements are planned for version 9.

WalkerJ, about the cursor issue, can you do the following when the problem occurs? Enable “Show remote cursor pointer” in the Input menu, and check whether the remote cursor moves or not.

For me, I don’t see the remote cursor move when the problem occurs. The nice thing is that if I go to the menu and toggle “track remote cursor” off and on it starts working again, which is a great improvement over my previous solution of quitting and reopening.

I have a similar issue (client is M1 Mac, Sonoma 14.1, using full-screen on external monitor). Pointer appears a bit to the left of the “actual” pointer, so if I want to click on something, I have to move the mouse to the left by a particular fixed offset. When I click-and-hold, I can sometimes make the pointer briefly teleport to the right location.

I’m able to fix this issue temporarily by restarting the remote machine (sudo reboot, on Ubuntu 24.04).

Hi warbaker.
We confirmed that the original issue of this thread is a problem with our window not receiving events sometimes, for unpredictable reasons and without a clear events pattern to work around it. We’re still digging Apple events to find a fix.
However your case seems different, an offset can be caused by a problem in scaling the pointer coordinate. You said you run in fullscreen mode, what is the view mode: viewport (scrollbars or black area around the desktop), resize remote display or scaling?

Thanks for the reply, Tor.

I’ve tried all three modes, and get what looks like the same issue regardless.

Yeah, a scaling issue sounds right. I noticed that the offset between the visible mouse location and the actual location of pointer clicks is larger the farther right the mouse is. So, when the mouse is on the left side of the screen, and as I move it right the offset becomes larger.

I also see the issue if I toggle off full-screen mode.

I have confirmed that the resolution of the monitor is equal to the resolution of the remote machine (3840 x 2160).

If I reboot the remote machine, I am sometimes able to temporarily resolve the issue, but I use this as a dev machine, so this is not ideal (have a lot of open terminal windows, image viewers, etc).

We have opened a Trouble Report which you can monitor at the following link:
