On Linux the window-state plugin restored the saved size before GTK's decorations and output scale had settled, so the saved physical inner size went through the creation-time CSD/scale conversion and drifted on every restart (52 px per axis under Mutter, the remembered size collapsing on other setups), and maximize transitions overwrote the remembered normal size. Linux now builds project and settings windows hidden and restores them after the first configure, keeping the normal size apart from maximize, fullscreen and minimize, protecting it during transitions, and snapshotting each window before close instead of querying GTK during exit. The state file format is unchanged; macOS and Windows keep the plugin as before. Verified under Mutter and Weston: three restarts at 1234×678, three maximized restarts followed by unmaximize, the settings window, several project windows across a full exit, and window groups all restore exactly. macOS restore is unchanged. Not run: GNOME on real hardware, mixed-DPI monitors, X11. Fixes #594 Fixes #636

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.
Build
pnpm install
pnpm tauri dev
Rust 1.96, Node 22, pnpm and the Tauri prerequisites.
Native notebook execution tests are opt-in and need two distinct Python environments
with ipykernel installed:
OPENIDEA_TEST_PYTHON=/first/env/bin/python \
OPENIDEA_TEST_PYTHON_SECOND=/second/env/bin/python \
cargo test -p ide-notebook --test kernel_runtime -- --ignored --test-threads=1
