In all application you can't move mouse and write simultaneously. Test on Fedora 25 with wayland
Only with touchpad
Thanks for taking the time to report this. This bug report isn't very useful because it doesn't describe the bug well. If you have time and can still reproduce the bug, please read https://bugzilla.gnome.org/page.cgi?id=bug-writing.html and add a more useful description to this bug. When providing a better description, please reset the status of this bug report from NEEDINFO to its previous status.
Replicate bug is very simple. Open any application where you can write with keyboard, same as gnome-terminal, gedit or other. Now try moving the mouse cursor with the touchpad while typing from the keyboard. In everyday applications is not a serious problem, but it becomes impossible to play with so many games.
Just keep a finger pressed on any printable character and try to move the mouse while pressing. This behaviour obviously doesn't happen under X.
I can confirm, however I don't see how this is a gnome-shell issue... :)
Maybe it's libinput related. if we run libinput-list-devices my touchpad reports this option enabled: Disable-w-typing: enabled under dconf there is /org/gnome/desktop/peripherals/touchpad/disable-while-typing I've disabled the option and the issue is still there. It's not gnome shell but some other gnome component like gnome-settings-daemon or whatever.
