Steam's autoscroll worked, except when it didn't. Every report of that came down to the same thing: Steam started in a way that carried no -noverifyfiles, noticed the patched web helper script, put its own copy back, and spent the session without the flag. There is no way to make every possible way of starting Steam carry an argument - a game launcher, a shortcut, a terminal, another program calling `steam steam://` - so the patch stops depending on it. The check is on size and timestamp, not on content, so the patch is now written to look untouched: the bytes the flag costs come back out of the script's own comments, and the timestamp of the untouched copy is restored afterwards. The file Steam finds is exactly as long and exactly as old as the one it wrote. A client that verifies its files finds nothing to repair. -noverifyfiles stays as the fallback for a script with no comments left to pay for the flag. Two things fall out of that. A patch that keeps the size no longer has to wait for Steam to close, because there is no size mismatch for the client to chase; only the growing one still defers. And an installation patched by the earlier version is quietly redone at the original size on the next apply, so the fix arrives without anyone having to know about it. Then the launch paths that were never covered: - Shortcuts on the desktop itself. Nothing in the XDG search path looks at that folder, so nothing had ever seen them - and Steam writes one there for every game somebody asks for a shortcut to. Its name is translated, so it is read from user-dirs.dirs and handed to the watcher in a drop-in. - Steam as a Flatpak was never recognised as Steam, so its entry got nothing while its script got patched - the worst of both. The switch goes after the application id there, where flatpak passes it on rather than reading it. - steam-native and steam-jupiter, which are ordinary Steam starts under another name, and Flatpak and snap entries in ~/.config/autostart. Two things found on the way: a client update left the undo copy holding the script from before the update, so undoing would have put an old version back; and a shortcut edited in place and later deleted would have been recreated by `disable`.
