Slow when scrolling down a file while using nvim

[gerep]

What Operating System(s) are you seeing this problem on?

Linux X11

Which Wayland compositor or X11 Window manager(s) are you using?

I'm using the PoPOS Gnome.

WezTerm version

20240203-110809-5046fc22

Did you try the latest nightly build to see if the issue is better (or worse!) than your current version?

Yes, and I updated the version box above to show the version of the nightly that I tried

Describe the bug

On the left side, I'm running GNOME Terminal. On the right, Wezterm.

The slowness is evident when I scroll down or up the file.

Configuration

This is all my config—the one I use in the video.

-- Pull in the wezterm API
local wezterm = require 'wezterm'

-- This table will hold the configuration.
local config = {}

if wezterm.config_builder then
  config = wezterm.config_builder()
end

config.audible_bell = 'Disabled'
config.color_scheme = 'Rosé Pine Moon (Gogh)'
config.font = wezterm.font("Hack Nerd Font Mono", {weight="Regular", stretch="Normal", style="Normal"})
config.font_size = 12

-- timeout_milliseconds defaults to 1000 and can be omitted
config.leader = { key = 'a', mods = 'CTRL', timeout_milliseconds = 1000 }
config.keys = {
  {
    key = '%',
    mods = 'LEADER|SHIFT',
    action = wezterm.action.SplitHorizontal { domain = 'CurrentPaneDomain' },
  },
  {
    key = '$',
    mods = 'LEADER|SHIFT',
    action = wezterm.action.SplitVertical { domain = 'CurrentPaneDomain' },
  },
  -- Send "CTRL-A" to the terminal when pressing CTRL-A, CTRL-A
  {
    key = 'a',
    mods = 'LEADER|CTRL',
    action = wezterm.action.SendKey { key = 'a', mods = 'CTRL' },
  },
  {
    key = 'Z',
    mods = 'CTRL',
    action = wezterm.action.TogglePaneZoomState,
  },
}

return config

Expected Behavior

For the scrolling to be smooth as it is on Gnome Terminal.

Not entirely sure if this would solve your problem but have you tried max_fps?

same for me - X11, empty config. Scrolling is clunky. I compared to konsole where it also is smooth. Interestingly, I switched to Wezterm ~1y ago, because it was exactly the opposite.

I experience the same issue on Windows, compared to Windows Terminal scrolling in nvim is clunky/slower in wezterm. Tried changing gpu adapters but it didn't help
