spice-gtk / wayland / keyboard / dual screens

Hello, latest version of spice-gtk , gtk3 , weston from arch distribution. With two monitor ( dual gtk windows) there is a big latency when I click on CapsLock on the second windows. This latency seems to be 2secondes, relative to call of static void guest_modifiers_changed(SpiceInputsChannel *inputs, gpointer data)

• there's no issue with a single monitor configuration ( one qxl card)
• there's no issue with two monitor configuration with X11 or X-Wayland configuration.

It's very simple two reproduce, a Vm with two qxl card ( on windows ) . remote-viewer , plays with caps lock or numlock into each screen
