I also tested 18.04 again with another setup, still dual screen on a samsung TV, the vlc GUI is exageratly zoomed but still correctly visible and usable, not sure if they want it to be zoomed like that.

The laptop display cover is closed, the output is sent on an external LG TV with 1920x1080. This system has been working flawlessly for many years, resp. under late 14.04 and 16.04. After recently upgrading to 18.04, I noticed VLC wouldn't display correctly - see attachment. This only occurs on the external display ; if I open the cover and use the internal display, there is no problem - except I cannot work on the internal display. regards, J.-Luc ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: vlc-bin 3.0.4-1ubuntu0.2 ProcVersionSignature: Ubuntu 4.15.0-43.46-generic 4.15.18 Uname: Linux 4.15.0-43-generic x86_64 ApportVersion: 2.20.9-0ubuntu7.5 Architecture: amd64 CurrentDesktop: ubuntu:GNOME Date: Wed Jan 2 23:38:36 2019 ExecutablePath: /usr/bin/vlc InstallationDate: Installed on 2018-12-19 (14 days ago) InstallationMedia: Ubuntu 18.04.1 LTS "Bionic Beaver" - Release amd64 (20180725) ProcEnviron: PATH=(custom, user) XDG_RUNTIME_DIR=<set> LANG=fr_FR.UTF-8 SHELL=/bin/bash SourcePackage: vlc UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qtbase-opensource-src/+bug/1810346/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
