Does it happen every time?

It doesn't reproduce on my mac, hmmm

[MrStevns]

Yes it happens consistently.
I have tried to close and reopen focus too, it happens every time for me.

Ah another thing, my macbook is retina (2560x1600) while my second monitor is 1080p. Maybe the issue is caused by the difference in resolution.

Latest nightly too?

[MrStevns]

Yep, In nightly too.

I however just discovered that when you put the application in fullscreen, the problem gets resolved temporarily for that monitor and i can now also go back to windowed mode and it still works as expected.

When I move the window back to first monitor, the caret has been offset again but only for that monitor.

So the workaround for now is to put the application In fullscreen, whenever I move the window between monitors.

I have tried it on my macOS Sequoia with different monitors and different display resolutions, can't reproduce. Could be an older macOS issue, but unfortunately I don't have a Monterey machine to test it on.

I am able to reproduce this and it seems to happen when the window is moved to a display with a different backing scale factor. Here is a PR with a fix that at least works for me: #467

On my mac there seems to be no way to select a scaling factor for a display, but I played with different resolutions and wasn't able to reproduce it.
Maybe they "fixed" it in newer macOS's, but your fix seems reasonable, so we'll merge it, thanks!

@MrStevns please try this build https://drive.google.com/file/d/1Ue4L-zpOUs2Qc2WeN2MFuucIL-MCjV9F/view?usp=drive_link

I have macOS Sequoia 15.1 so I don't think it is "fixed" in newer versions. It is a 16 inch MacBook Pro with an external display with the resolution 2560x1440. I have not changed any other settings.

I also noticed the same issue when I "mirrored" my screen on a couple of different TVs. Not sure about the resolution of those.

(contd.) The MacBook screen reports a backing scale factor of 2 and the external display 1 with that configuration.
