Describe the bug

After run wezterm first time copy mouse selection to clipboard (CopyTo("Clipboard")) works properly. Second selection seen in clipboard on guest machine, but host still see first selection. In rxvt-unicode and kitty all work as expected.

To Reproduce

VirtualBox with Ubuntu 20.04 (guest) on Windows laptop (host).

• run wezterm
• in wezterm select something (sel1) by mouse and press key to copy to clipboard
• on Windows paste from clipboard - work properly
• select another text (sel2) in wezterm and copy it to clipboard
• on Windows paste from clipboard - still sel1 instead of sel2. On guest machine 'xsel -o -b' shows sel2 as expected.

Configuration

wezterm.lua only configure shortcuts.

Expected Behavior

Each selection copied to clipboard should be seen in host machine.

If the selection has the correct values inside the VM and you're able to copy and paste between apps inside the VM then it sounds like an issue with the VM integration layer. If I were you, I would search for other similar sounding issues with virtualbox to see if that gives some clues on what to dig into next.

@wez It seems, like VirtualBox problem and I find that what may be wrong. I opened the issue, because the problem exists only in WezTerm.

I understand, but a VM is, by design, not visible to the programs that run inside. If the guest works correctly then there's something about the VM interaction causing the issue.

I don't use the environment that you are running in, and don't have the time to replicate the system of everyone that encounters problems: there is just one of me and I am massively outnumbered by wezterm users.

That means that it is up to you to dig into this more deeply to get more information about what is going wrong. I'd be happy to consider any additional information you can provide.

I made workaround (like neovim works), may be it can help to understand the problem.

{key="w", mods="WIN", action=wezterm.action_callback(function(win, pane)
    local sel = win:get_selection_text_for_pane(pane)
    wezterm.background_child_process{"bash", "-c", "printf " .. sel .. "| xsel -b"}
    end)
},
