bug: Flash plugin doesn’t work as expected

[cbconne]

Check the following:

• I have tried setting vscode-neovim.neovimClean in VSCode settings and restarting VSCode.
• I have read the vscode-neovim docs.
• I have searched existing (closed!) issues.

Neovim version (nvim -v)

NVIM v0.11.5 Build type: Release

VSCode version and flavor (Cursor, vscodium, …)

VSCode 1.106.0

Operating system/version

macOS 26.1

Problem (including log messages)

When using Neovim with the Flash plugin, Flash doesn’t behave as expected.
Similar to vscode-neovim discussion #2514.

I have already tried setting "editor.accessibilitySupport": "off", with the following behavior:

Flash works correctly on the initial launch of VSCode.
However, as soon as I switch to another window and come back, it's wrong. In fact, simply losing focus triggers the issue.

Steps To Reproduce

1. Open VSCode, flash works correctly;
2. switch to another window and come back, it's wrong.

Expected Behavior

Flash work correctly as first open VSCode.

Please update the title.

Sure, my mistake.

Which of the workarounds in #2514 did you try, specifically?

1. Update VScode;
2. Explicitly setting "editor.accessibilitySupport": "off" and restarting VSCode.

With the setting, it could work until losing focus.
