Created attachment 1334858 [details] Comparison between Wayland and XWayland animations screencast Description of problem: The new GNOME 3.26 window maximize animations don't work on native Wayland apps under GNOME Wayland session, but it does work on XWayland apps! Also, In Nautilus (Files) only; the hotkeys are different (Super + Left/Right should move the tiled app to the opposite side if the opposite arrow key is used, but it move it first to the original sized window first, then pressing it again moves it to the tiled sized window on the opposite direction). Maybe, this is related or needs a separate bug for it. Version-Release number of selected component (if applicable): gnome-shell-3.26.0-1.fc27.x86_64 mutter-3.26.0-4.fc27.x86_64 gedit-3.22.1-2.fc27.x86_64 nautilus-3.26.0-1.fc27.x86_64 slack-2.8.1-0.1.fc21.x86_64 How reproducible: Always Steps to Reproduce: 1. Open a native GNOME Wayland app like Nautilus or GEdit. 2. Maximize the window using Super + Up. 3. Half-tile the window to the right and the left using Super + Right/Left. Actual results: The window moves directly to the desired state without any animations more than a small fade-out/in. Expected results: The window uses the right animations. Additional info: I reported this against GNOME Shell component, but maybe it should be mutter, I really don't know. Also I couldn't find the tracking bug of the feature itself here or on GNOME bugzilla; other that it was worked on in GUADEC in @mcalsen blog: https://blogs.gnome.org/mclasen/2017/06/08/rawhide-sightings/
I've just switched to the Xorg session and noticed that those apps (GTK3 Wayland apps like Nautilus and GEdit) work flawlessly under X.
