From 21e2f6e13dc3109469e82868c4fed78bb5fa7bbf Mon Sep 17 00:00:00 2001 From: weidu12123 Date: Fri, 16 Oct 2026 22:53:46 +0800 Subject: [PATCH] docs: state the desktop memory numbers without overselling them The table listed "never opened the window" next to "closed to tray" without saying what separates them, and the closing line claimed the tray state was where the app spends most of its time -- implying the 5 MB figure applies there. It does not. The distinction is whether the WebView was ever created, not whether the window is currently visible: hiding only drops it to WebView2's low memory level, so after the first time the window is opened, closing to tray leaves ~180 MB resident until the process restarts. Only an autostart instance that was never opened sits at 5 MB. Also note the cost of going further (destroying the WebView on hide): a reload on reopen, and the open tabs are lost today because the frontend does not persist its layout.
