lspsaga.nvim光标移动时屏幕水平闪烁问题求助

• 问题现象：使用lspsaga.nvim时，移动光标会触发屏幕水平闪烁，关闭该插件后问题消失，可确定由lspsaga引发
• 已尝试方案：将code_action设为空字符串，未解决问题

我的lspsaga配置代码：

local status, saga = pcall(require, "lspsaga")
if (not status) then return end

local keymap = vim.keymap.set

saga.setup{
ui = {
-- currently only round theme
theme = 'round',
-- this option only work in neovim 0.9
title = false,
-- border type can be single,double,rounded,solid,shadow.
border = 'rounded',
winblend = 6,
expand = '',
collapse = '',
preview = ' ',
code_action = '💡',
diagnostic = '',
incoming = ' ',
outgoing = ' ',
colors = {
--float window normal background color
-- normal_bg = '#232136',
},
kind = {},
},

preview = {
lines_above = 1,
lines_below = 10,
},
scroll_preview = {
scroll_down = '<C-f>',
scroll_up = '<C-b>',
},
request_timeout = 2000,

finder = {
edit = { 'o', '<CR>' },
vsplit = 's',
split = 'i',
tabe = 't',
quit = { 'q', '<ESC>' },
},
-- ライトバルブをすべて無効
lightbulb = {
enable = false,
enable_in_insert = false,
sign = false,
sign_priority = 40,
virtual_text = false,
},

diagnostic = {
show_code_action = false,
show_source = true,
jump_num_shortcut = true,
keys = {
exec_action = 'o',
quit = 'q',
go_action = 'g'
},
},
-- winbarのシンボルを無効化
symbol_in_winbar = {
enable = false,
separator = ' ',
hide_keyword = true,
show_file = true,
folder_level = 2,
respect_root = false,
color_mode = true,
},
}

解决建议 #

• 调整UI透明度：将配置中ui.winblend的值改为0，半透明窗口渲染可能和终端/Neovim的渲染机制冲突，导致闪烁
• 更换边框样式：把ui.border从rounded替换为solid或single，圆角边框的动态渲染可能存在性能问题
• 升级lspsaga到最新版本：旧版本可能存在未修复的渲染bug，执行插件更新命令（比如PackerSync或LazyUpdate）后重试
• 禁用所有动态UI元素：暂时关闭diagnostic相关的动态提示，或者尝试使用极简配置启动lspsaga，逐步排查触发闪烁的组件
• 检查Neovim版本：确保使用Neovim 0.9.x及以上的稳定版本，旧版本的窗口API可能存在兼容性问题
