** Description changed: Summary On Ubuntu 26.04 LTS with GNOME Shell 50.1 running under Wayland, the GNOME top bar remains visible when launching World of Warcraft through Battle.net/Lutris in Windowed (Fullscreen) mode. The issue is 100% reproducible. An upstream report has already been opened against GNOME Mutter: https://gitlab.gnome.org/GNOME/mutter/-/work_items/4911 System information Distribution Ubuntu 26.04 LTS Desktop GNOME Shell 50.1 Session Wayland Hardware Lenovo ThinkPad P14s Gen 5 AMD AMD Ryzen 5 PRO 8640HS AMD Radeon 760M Graphics (RADV) Mesa 26.0.3-1ubuntu1 Internal display (1920×1200 @ 60 Hz) Software Lutris 0.5.22 (.deb package) Gamescope 3.16.20 GE-Proton (UMU runtime) Battle.net World of Warcraft Classic Steps to reproduce Log into an Ubuntu Wayland session. Launch Battle.net from Lutris. Launch World of Warcraft. Open Graphics settings. Select Windowed (Fullscreen). Use the native display resolution (1920×1200). Return to the game. Expected result The GNOME top bar should automatically hide while the game occupies the entire display. Actual result The GNOME top bar remains permanently visible above the game. The game renders correctly but does not cover the top panel. Additional observations Switching the game to Fullscreen hides the GNOME top bar correctly. However, this display mode causes input/UI issues, making it unusable. The issue only affects Windowed (Fullscreen) mode. Troubleshooting performed The problem has been reproduced after testing: Lutris Flatpak Lutris native (.deb) GE-Proton UMU runtime DXVK enabled VKD3D enabled Esync enabled Fsync enabled GameMode enabled The behavior is identical in every configuration. Gamescope comparison Launching the exact same game through Gamescope correctly hides the GNOME top bar. Gamescope is not required to reproduce the issue; it is only used as a comparison. GNOME Extensions The issue is reproducible with the default Ubuntu session. Disabling all non-default GNOME extensions does not change the behavior. Upstream report This issue has already been reported upstream to the GNOME Mutter developers: https://gitlab.gnome.org/GNOME/mutter/-/work_items/4911 If this is confirmed as an upstream Mutter issue, this Launchpad report can be linked to the upstream report for tracking within Ubuntu. Reproducibility Always (100%).
