youngledoandyoungledo fca9d1e08f fix(window): keep merged project tabs from moving the frame or menu bar (#1697)
Merged project tabs are separate native windows. Switching tabs copied the selected frame with Tauri's position and size setters, which only queue the change, while macOS orders the shown window front at once, so the old rectangle appeared and then slid into place; two maximized windows could also share the maximized flag with different rectangles, so the copy was skipped. On macOS the AppKit frame is now written synchronously and the window is shown in the same turn, with frame constraining suspended for that write; elsewhere a differing outer rectangle is always assigned. A source window in native fullscreen still hands fullscreen over as before.

Focusing another project window re-pushed the shared menu config and replaced the macOS menu bar even when nothing changed; an identical config no longer rebuilds the menu.

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.

Plugins

Plugins add actions, completion, quick fixes, tool windows, custom editors, themes, file icons and languages. They run as sandboxed WebAssembly components; themes, icon themes and languages need no code at all.

Install them from Settings › Plugins, or start your own with openidea-plugin new — see Writing OpenIDEA plugins and the official plugins. The plugin API is still a preview.
