Bouncy buffer

[NicolasGB]

I've noticed on versions > 1.2.3 that the text bounces.

It looks like it happens with lines that fill the buffer window when the wrap is activated, and on the lines that overflow, i've tried to reproduce it and find a reliable way of doing so, but haven't been able to.

It happens in both 1.2.4 and 1.2.5, but when i go back to 1.2.3 the bouncing never appears.

Here's a video of what's happening:

To reproduce i've used this minimal lua file:

vim.env.LAZY_STDPATH = ".repro"
load(vim.fn.system("curl -s https://raw.githubusercontent.com/folke/lazy.nvim/main/bootstrap.lua"))()

require("lazy.minit").repro({
	spec = {
		{
			"mrcjkb/rustaceanvim",
			version = "^4",
			init = function()
				-- Configure rustaceanvim here
				vim.g.rustaceanvim = {}
			end,
			lazy = false,
		},
		{
			"williamboman/mason.nvim",
			config = function()
				require("mason").setup({})
			end,
		},
		{
			"neovim/nvim-lspconfig",
		},
		{
			"declancm/cinnamon.nvim",
			-- version = "1.2.3",
			config = function()
				require("cinnamon").setup({
					keymaps = { extra = false },
				})
				local cinnamon = require("cinnamon")

				-- Toggle scrolling off in large fields
				vim.keymap.set("n", "<leader>ts", function()
					require("cinnamon.config").disabled = not require("cinnamon.config").disabled
				end, { desc = "Toggle smooth scrolling" })

				-- Centered scrolling:
				vim.keymap.set("n", "<C-u>", function()
					cinnamon.scroll("<C-u>zz")
				end)
				vim.keymap.set({ "n", "x" }, "<C-d>", function()
					cinnamon.scroll("<C-d>zz")
				end)
				vim.keymap.set({ "n", "x" }, "G", function()
					cinnamon.scroll("Gzz")
				end)

				-- Line scroll
				vim.keymap.set({ "n", "v" }, "H", function()
					cinnamon.scroll("^")
				end)
				vim.keymap.set({ "n", "v" }, "L", function()
					cinnamon.scroll("$")
				end)
				vim.keymap.set({ "n", "x" }, "0", function()
					cinnamon.scroll("0")
				end)

				-- End
				vim.keymap.set({ "n", "x" }, "e", function()
					cinnamon.scroll("e")
				end)
				vim.keymap.set({ "n", "x" }, "E", function()
					cinnamon.scroll("E")
				end)
				-- Backward
				vim.keymap.set({ "n", "x" }, "b", function()
					cinnamon.scroll("b")
				end)
				vim.keymap.set({ "n", "x" }, "B", function()
					cinnamon.scroll("B")
				end)
				-- Down
				vim.keymap.set({ "n", "x" }, "j", function()
					cinnamon.scroll("j")
				end)
				-- Up
				vim.keymap.set({ "n", "x" }, "k", function()
					cinnamon.scroll("k")
				end)
			end,
		},
	},
})

And i've scrolled with j and k plenty of times through the long lines of this file: https://github.com/NicolasGB/filecrab/blob/main/filecrab-server/src/main.rs

I know it's not the best way to reproduce it, but hopefully it helps.

Let me know if i can provide more information
