Yes disabling fullscreen window "unredirection" should work, and was discussed in the previous bug too (bug 1862081).

Other websites, like Netflix, will fullscreen for a second and de-fullscreen after that. Some games act weirdly in fullscreen mode (this might be related, as I've never had this issue before now: https://github.com/ValveSoftware/csgo-osx- linux/issues/2429). EDIT: This only happens when fractional scaling is enabled. My config; main 4K screen at 150% and secondary 1080p screen to the right at 100%. YouTube fullscreens fine on the sec. screen (1080 100%). This is a gif I posted in the related bug report showing exactly what happens: https://bugs.launchpad.net/ubuntu/+source/gnome- shell/+bug/1863391/+attachment/5397743/+files/20200731_160007.gif ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: mutter 3.36.3-0ubuntu0.20.04.1 ProcVersionSignature: Ubuntu 5.4.0-42.46-generic 5.4.44 Uname: Linux 5.4.0-42-generic x86_64 ApportVersion: 2.20.11-0ubuntu27.4 Architecture: amd64 CasperMD5CheckResult: skip CurrentDesktop: ubuntu:GNOME Date: Mon Aug 3 14:03:00 2020 InstallationDate: Installed on 2020-07-30 (4 days ago) InstallationMedia: Ubuntu 20.04 LTS "Focal Fossa" - Release amd64 (20200423) SourcePackage: mutter UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1890141/+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
