Just tested in a fully up-to-date Kubuntu 20.04 VM (amd64), and I cannot observe the problem. Printing an e-mail does pop up the print dialog in front of the thunderbird window.
Can you share the exact steps you're taking to reproduce the problem? Can you maybe attach a screencast demonstrating it? ** Changed in: thunderbird (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to thunderbird in Ubuntu. https://bugs.launchpad.net/bugs/1887433 Title: Print dialog from Thunderbird appears behing thunderbird window Status in thunderbird package in Ubuntu: Incomplete Bug description: When you print from Thunderbird the print dialog appears behind the main Thunderbird window. Of course, it should appear in the front of Thunderbird. You can reproduce it every time. Mozilla developers say this window is a part of Ubuntu and NOT of Thunderbird. (Also this window is NOT transalated to German fully - but for this I opened a separate bug already) ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: thunderbird 1:68.10.0+build1-0ubuntu0.20.04.1 ProcVersionSignature: Ubuntu 5.4.0-40.44-generic 5.4.44 Uname: Linux 5.4.0-40-generic x86_64 NonfreeKernelModules: wl ApportVersion: 2.20.11-0ubuntu27.3 Architecture: amd64 BuildID: 20200629235513 CasperMD5CheckResult: skip CurrentDesktop: KDE Date: Mon Jul 13 22:29:20 2020 DefaultProfileExtensions: extensions.sqlite corrupt or missing DefaultProfileIncompatibleExtensions: Unavailable (corrupt or non-existant compatibility.ini or extensions.sqlite) DefaultProfileLocales: extensions.sqlite corrupt or missing DefaultProfilePrefErrors: Unexpected character ',' before close parenthesis @ /usr/lib/thunderbird/omni.ja:greprefs.js:1138 DefaultProfileThemes: extensions.sqlite corrupt or missing InstallationDate: Installed on 2020-07-12 (0 days ago) InstallationMedia: Kubuntu 20.04 LTS "Focal Fossa" - Release amd64 (20200423) Profiles: Profile1 (Default) - LastVersion=None/None (Out of date) Profile0 - LastVersion=68.10.0/20200629235513 (In use) SourcePackage: thunderbird UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thunderbird/+bug/1887433/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
