Description of problem: I can reliably reproduce a problem where your cursor gets hidden after hovering over youtube videos and does not get displayed anywhere in Firefox (even outside the video area) until you leave the app completely. This only happens on Wayland, and curiously enough, it only seems to happen for monitors in pivoted mode. See the attached video. Version-Release number of selected component (if applicable): firefox-49.0-2.fc25.x86_64 gnome-session-wayland-session-3.22.1-2.fc25.x86_64 gnome-shell-3.22.1-2.fc25.x86_64 gtk3-3.22.2-1.fc25.x86_64 libwayland-client-1.12.0-1.fc25.i686 libwayland-client-1.12.0-1.fc25.x86_64 libwayland-cursor-1.12.0-1.fc25.x86_64 libwayland-server-1.12.0-1.fc25.i686 libwayland-server-1.12.0-1.fc25.x86_64 mesa-libwayland-egl-12.0.3-3.fc25.x86_64 mutter-3.22.1-5.fc25.x86_64 xorg-x11-server-Xorg-1.19.0-0.2.20160929.fc25.x86_64 xorg-x11-server-Xwayland-1.19.0-0.2.20160929.fc25.x86_64 How reproducible: always (for my setup) Steps to Reproduce: 1. have two monitors, the left in landscape mode, the right in pivoted mode (top-aligned, resolutions should not matter) 2. run gnome wayland session 3. run youtube in firefox, make sure a video is playing (it must not be stopped, that doesn't hide the cursor) 4. move the cursor from the left monitor to the video area on the right monitor quickly. The cursor should disappear instantly, and it should not reappear even if you leave the video area and move around in the browser. Try a few times if needed. 5. move the cursor outside of firefox window, the cursor should reappear 6. perform 4) again, but this time slowly, going over a piece of non-video-area firefox window. The cursor should not get hidden immediately (but after a few second delay) and it should reappear immediately after leaving the video area. Additional info: This only seems to happen for pivoted monitors (I can't reproduce that with two monitors in landspace mode), and only if you enter the video area quickly enough. I could not reproduce the same problem with totem or vlc.

Olivier Fourdan confirmed he can reproduce this issue even in Weston and even using Google Chrome.
