Hi, The subwindows are not dependent of the windows manager or compositor. It's a system designed by the Qt framework and, unfortunately, theming it with style introduces new bugs. This topic was discussed on Krita-Artist forum four days ago here: https://krita-artists.org/t/extra-doc-title-bar-when-multiple-documents-are-opened-in-windowed-mode-is-this-ui-behavior-changeable/42822?u=deevad I'm closing this report as a 'Resolved' to close it, and 'Intentional' because it is wanted to not try to theme the subwindows because that would create other bugs. Sorry and thank you for the bug report.
