Fullscreen applications breaks under mosh 1.4.0 on MacOS 15.4
Hello,
I have just received a brand new Air 15 M3 with MacOS Sequoia 15.4, installed mosh 1.4.0 via brew and connected to my Fedora in the MacOS built-in Terminal app.
After some time of editing in Vim the session gets broken, it looks like everything is shifted one line upwards, things are breaking, I am not entirely sure what is wrong. When I delete a line, it deletes a line above the cursor and the status line of vim updates one line below where it should render. Clearing the session with Ctrl-L does not help.
I customized the Terminal a bit in Settings, I will try to revert to default values but wanted to open up this issue first. Here is how it looks like:
I did not have this problem on Pro 16 M1 which also had the same OS version and I also exclusively only used the built-in Terminal app. Not sure what is different, I guess mosh version is new I did not upgrade too often.
For the record, here is my settings of the Terminal.app:
