+++ This bug was initially created as a clone of Bug #757942 +++

> On Fedora 23 with gnome-shell-3.18.1-1.fc23.x86_64 under Wayland, when computer is under heavy load (for example, several VMs are running), if computer "freezes" because of that heavy load, input event is send repeatedly.
> 
> E. g. when I had several VMs running and I was typing in Firefox, characters were appearing repeatedly (I was trying to type "properly", but I have instead typed "prrrrrrrrrrrrrrrrrrrrroperly"). On another occasion, I wanted to start Emacs from Overview, I have clicked its icon and it started five times.

According to different comments of that Bug #757942, the issue is still
present. It seems to affect both XWayland (e.g. Firefox, Texstudio) and pure
wayland (e.g. Gedit) applications and is not limited to Gtk+ (Firefox, Gedit),
but also affects Qt5 (Texstudio) applications. Also happens to gnome-shell
activities overview search.

Since nobody cares to reopen the bug, I'm cloning it. I changed the product to
gnome-shell, because it is not limited to Gtk+ applications. Please note that I
don't know where this bug comes from, it could e.g. be deep in the libwayland
stack.

Installed software versions:
gnome-shell-3.22.2-2.fc25.x86_64
libwayland-client-1.12.0-1.fc25.x86_64
