Windows 10 - CTRL + SHIFT + v pastes blank into WSL2 but fine if to Powershell

[erfianugrah]

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

Windows

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

No response

WezTerm version

wezterm 20240429-102818-0184e88e

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

Copy pasting issues. Happens with both Ditto and Windows Clipboard, when trying to paste into WSL2 from the system, clipboard creates a blank entry instead, so I need to delete that entry and force the initial entry to paste the actual values, but it'll paste with CRLF instead of LF, so I forced LF for now, but the blank pasting is still a problem. Also tried to disable win32 input just to see, but same thing

To Reproduce

Normal copy paste to reproduce

Configuration

-- Pull in the wezterm API
local wezterm = require("wezterm")

-- This will hold the configuration.
local config = wezterm.config_builder()
local gpus = wezterm.gui.enumerate_gpus()
local act = wezterm.action
-- Theme
config.color_scheme = "lovelace"

-- Window Size
config.initial_rows = 40
config.initial_cols = 160

-- Cursor
config.default_cursor_style = "BlinkingBar"

-- FPS
config.animation_fps = 120

-- GPU Acceleration
config.front_end = "WebGpu"
config.webgpu_preferred_adapter = gpus[1]

--Scrollback
config.scrollback_lines = 5000
config.debug_key_events = true

-- Windows
if wezterm.target_triple == "x86_64-pc-windows-msvc" then
	-- Paste Action
	config.keys = {
		-- paste from the clipboard
		{ key = "V", mods = "CTRL", action = act.PasteFrom("Clipboard") },
		-- paste from the primary selection
		{ key = "V", mods = "CTRL", action = act.PasteFrom("PrimarySelection") },
		-- test
		{ key = "v", mods = "CTRL", action = act.Nop },
	}
	config.canonicalize_pasted_newlines = "LineFeed"
	config.allow_win32_input_mode = false

	-- GPU
	config.front_end = "WebGpu"
	config.webgpu_preferred_adapter = gpus[1]

	-- WSL
	config.default_domain = "WSL:Ubuntu"
	config.default_cwd = "/home/erfi"
	config.launch_menu = {
		{
			label = "PowerShell",
			domain = { DomainName = "local" },
			args = { "powershell.exe", "-NoLogo" },
		},
	}
end

-- Keybind for launch_menu
config.keys = {
	{ key = "l", mods = "ALT", action = wezterm.action.ShowLauncher },
}
-- Fonts
config.font = wezterm.font({ family = "IosevkaTerm NF", weight = "Regular" })
config.font_size = 11.5
config.line_height = 1

-- Window Close Prompt
config.window_close_confirmation = "NeverPrompt"

-- and finally, return the configuration to wezterm
return config

Expected Behavior

On MacOS and SteamDeck, the copy paste functionality is as intended, CTRL-C or CMD-C then CTRL-SHIFT-v/CMD-SHIFT-v just pastes the content

Anything else?

I digged a little more, and it seems to do with the usage of Tmux, however I have no clue as to why tmux would interfere, also it does interfere with wezterm settings like the cursor style, BlinkingBar for instance never persists once I got from terminal to editing things on nvim, then back out, it goes back to block. And this only seems reproducible for windows, Window Terminal has a different copy-paste shortcut, so it's just CTRL-V and that works with Tmux
