NOTE: the warning that linked you to this page is probably a red herring. GTK Session Lock has a hard time explicitly supporting each version of GTK, but new unsupported versions almost always work in practice.
Due to limitations of GTK, GTK Session Lock depends on unstable GTK internals. Each release works with all versions of GTK >=3.22.0 at the time of release, but future GTK updates may occasionally break them. See gtk-priv/README.md for more details.
The table below shows which GTK Session Lock versions work with which GTK versions. If there is a mistake, missing info or you have any other questions, please open an issue.
| GTK Session Lock | Explicitly supported GTK | Highest GTK known to work | GTK versions known to crash |
|---|---|---|---|
| v0.1.0 | v3.20.0 - v3.24.39 | v3.24.39 | - |
