Public bug reported: Some applications are missing the titlebar in gnome-session-flashback with Metacity. Standard GNOME applications are not affected, but some that use Xlib directly, like mupdf or feh, are.
Steps to reproduce: - Use mupdf to display any .pdf file, or use feh to display any image file. Expected result: - A window with a title bar appears. Actual result: - A window without title bar, but thicker borders, appears. - This does not always happen; sometimes, the title bars appear just fine. - see attached screenshot Things I tried: - Enabling/disabling org.gnome.metacity.compositing-manager via dconf-editor doesn't make a difference. - In an Xlib-based program I wrote myself, I could get rid of this by doing a dummy call to XSetWMNormalHints() with BaseSize set to the window size I was using anyway and MinSize set to 1x1. metacity: Installed: 1:3.18.3-1ubuntu2 Candidate: 1:3.18.3-1ubuntu2 Version table: *** 1:3.18.3-1ubuntu2 500 500 http://mirror.dreamchip.de/ubuntu xenial/main amd64 Packages 100 /var/lib/dpkg/status Description: Ubuntu Xenial Xerus (development branch) Release: 16.04 ** Affects: metacity (Ubuntu) Importance: Undecided Status: New ** Attachment added: "demo of the missing titlebar bug" https://bugs.launchpad.net/bugs/1568852/+attachment/4632707/+files/metacity_titlebar_bug.png -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to metacity in Ubuntu. https://bugs.launchpad.net/bugs/1568852 Title: missing title bar for some applications To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/metacity/+bug/1568852/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
