Additional context Try to reproduce the problem with kitty --config NONE if you cannot then post a minimal kitty.conf that reproduces the problem. If the problem involves interaction with some other terminal program post a minimal config for that program to reproduce the problem as well.

You havent posted the full debug output.

@kovidgoyal Sorry, Kitty seems to copy only the current screen in scroll mode even when I select the whole text. Is this behaviour expected? If not, I can create another ticket for that. I have updated the ticked with the whole debug output

[kovidgoyal]

Your version of kitty is outdated, first update and see if you can reproduce. Because I cannot reproduce using current kitty. And the debug output is opened in less, copying using kitty copy can only copy a screenfull since less only displays a screenfull at a time. And note that debug output is copied to theclipboard automatically.
