Yes. twm has absolutely no support for the _NET_WM protocol / Exentend Windows Manager Hints(1) that have been introduced more than 15 years ago, and are required by most "modern" toolkits (gtk/qt) for at least 10 years. We should have removed twm(1) from xenocara a long time ago since there is no developer interest to "modernize" it by implemnting those features.
