- The IDE is a GUI-subsystem binary, so Windows allocated a fresh console
window for every console-subsystem child it started: one black window per
language server, per settings-driven restart, per debug adapter and per
toolchain probe, titled with the child's own path. Closing it killed the
child, which is how editing the language-server settings broke highlighting.
- Peer::spawn, the spawn point for every language server, wired stdio but never
passed CREATE_NO_WINDOW. The rustup-proxy probe, the DAP adapter, debugpy
probe, runInTerminal and cargo spawns, the SDK probes, the run-configuration
probes, the coverage exporter and tool diagnostics/downloads (curl, tar) had
the same gap, while git, cargo builds, gh, docker and run configurations
passed the flag inline — five copies of the magic constant, six subsystems
without it.
- Add ide_core::process::{CREATE_NO_WINDOW, hide_console_window} as the single
definition, route every spawn through it (tokio commands via as_std_mut()) and
fold the inline copies into it.
- Verified locally on Windows with a console-detached harness: a plain spawn
reports a visible console window (GetConsoleWindow + IsWindowVisible), the
patched Peer::spawn reports a console without a window. cargo check, cargo
clippy --all-targets and the affected test suites (249 tests) are green.

OpenIDEA brings the IntelliJ IDEA way of working — its keymap, its tool windows, its search-everything habits — to a native app with a Rust core.
Editor, code insight, debugger, Git, terminal, database and HTTP clients, for 60+ languages. Builds for macOS, Windows and Linux.
Benchmark
Opening freqtrade (Python, ~770 files) with warm caches, median of 5 runs:
| OpenIDEA | IntelliJ IDEA 2026.2.3 | |
|---|---|---|
| Window with the project | 0.9 s | 3.1 s |
| Ready (CPU settled) | 1.1 s | 13.2 s |
| Memory (USS, all processes) | 169 MB | 2011 MB |
| CPU time until ready | 2.4 s | 47.9 s |
| Idle CPU | 4 % of a core | 7 % of a core |
| Quit | 0.3 s | 5.9 s |
A release build of OpenIDEA from main and IDEA with default settings and plugins, on
Windows 11, 32-core AMD, 62 GB RAM.
IDEA analyses Python more deeply, so "ready" doesn't mean the same work on
both sides. Both are measured from the outside, the same way: see
perf/compare to run it on your machine and projects.
