WezTerm version

wezterm 20230221-203743-e6ffeaf2

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

The problem appears when I am doing development in neovim on windows with multiple related plugins. The Terminal suddenly becomes completely corrupted. This does not happen after a specific time or combination of keypresses; it can be cursor movement, search, ...

This does not happen in other terminals Alacritty, ConEmu or Putty and does not seem to happen in Wezterm if I disable all my plugins. I suspect that it can be related to a plugin that asynchronously changes the UI like Treesitter for syntax highlightning or an LSP callback that trigger.

To Reproduce

I wish that I had some concrete, reproducible steps that I can list here, but I don't, so take this for what it's worth. It happens consistently in both in the latest stable and nightly

Configuration

local wezterm = require 'wezterm' local act = wezterm.action

return { color_scheme = "Nebula (base16)", font_size = 8, 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' },

-- THIS IS JUST HERE TO SEE IF I WAS ABLE TO FIX THE CORRUPTION. IT DID NOT HELP: { key = 'K', mods = 'CTRL|SHIFT', action = act.Multiple { act.ClearScrollback 'ScrollbackAndViewport', act.SendKey { key = 'L', mods = 'CTRL' }, }, }, }, }

Expected Behavior

No response

This is an issue with your graphics drivers. Try using the WebGPU front end: https://wezfurlong.org/wezterm/config/lua/config/front_end.html#webgpu

+1 I have not experienced the problem since changing the front end.
