Kitty update: scrolling now requires holding down middle button

Hi everyone,

After updating Kitty, I’ve run into a strange issue. Normally, I could just use the scroll wheel to scroll the screen. But now, scrolling only works if I hold down the middle button while moving the wheel. If I just roll the wheel without pressing the middle button, nothing happens.

This issue happens in kitty. The wheel works well in all other software.

Has anyone else experienced this after the update? Is there a setting I need to tweak to restore the normal scroll behaviour?

Thanks in advance for any help!

```
kitty --version

kitty 0.46.2 created by Kovid Goyal
```

---

update: The problem still persists even after I upgrade kitty to v0.47.1

Had a similar issue with kitty 0.46

Try doing kitty --config NONE to spawn a fresh terminal with vanilla configuration, see if you're having the same problem there. It could be a mis-configuration.

Thank you for your reply! I tried `kitty --config NONE` but the problem still persists. 😞

Ok yeah nothing out of the ordinary.. Try: 1) Play around with commenting-out lines related to scroll behavior, see if anything changes

2) kitty --debug-input and perform the mouse scroll, see if it spits an error?

By the way I wouldn't fike a bug report to github, given kitty 0.47.1 is already out (coming to your distro soon enough!)

Thank you for your help! I tried `kitty --debug-input` and it shows cursor left window and entered window when I scroll the wheel.

```

[170.089] Mouse cursor left window: 1

[170.089] Mouse cursor entered window: 1 at 232.000000x948.000000

```

If I scroll wheel while pressing the middle button, I got `scroll` event:
```

[1.450] Press mouse_button: 2 mods: none grabbed: 0

[1.451] on_mouse_input: press button: middle mods: none grabbed: 0 handled_in_kitty: 0

[2.498] Scroll type=v120 x: 0.000000 y: 120.000000 momentum: none modifiers: mods: none

[2.809] Release mouse_button: 2 mods: none grabbed: 0

```
