** Description changed: When scaling the desktop to e.g. 150%, fullscreen video does seem to trigger constant changes of the scaling factor: the system switches every 0.5s from 150% to 100% to 200% or things like those. The problem does not occur, when there is another windows present (e.g. a "always-on-top" terminal windows). Also, KDE doesn't have this problem. The problem exists in freshly installed 19.10 and 20.04, too. I couldn't find any reason, why sometimes firefox fullscreen videos do work and sometimes not. Video playback (e.g. GNOME video player or VLC) does not work properly in 19.10, whereas it works most of the time in 20.04. How can I help to dig into this? 1) Ubuntu 19.10, 20.04 2) latest available (problem exists since several weeks) 3) What you expected to happen: fullscreen video playback in scaled mode 4) What happened instead: screen starts changing (randomly?) the scaling factor or at least this is the impression one gets + --- + ProblemType: Bug + ApportVersion: 2.20.11-0ubuntu16 + Architecture: amd64 + CurrentDesktop: ubuntu:GNOME + DisplayManager: gdm3 + DistroRelease: Ubuntu 20.04 + InstallationDate: Installed on 2020-01-31 (19 days ago) + InstallationMedia: Kubuntu 20.04 LTS "Focal Fossa" - Alpha amd64 (20200130) + Package: gnome-shell 3.34.3-1ubuntu1 + PackageArchitecture: amd64 + ProcVersionSignature: Ubuntu 5.4.0-12.15-generic 5.4.8 + RelatedPackageVersions: mutter-common 3.34.3-1ubuntu1 + Tags: focal + Uname: Linux 5.4.0-12-generic x86_64 + UpgradeStatus: No upgrade log present (probably fresh install) + UserGroups: adm cdrom dip lpadmin lxd plugdev sambashare sudo + _MarkForUpload: True ** Attachment added: "Dependencies.txt" https://bugs.launchpad.net/bugs/1863391/+attachment/5329596/+files/Dependencies.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1863391 Title: GNOME fractional scaling: fullscreen video misbehaves To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1863391/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
