Zoom effect uses more gpu and gpu resources.

Description:
Zoom effect uses more gpu and gpu resources when in use. When the zoom effect is in use, it seems to me that Wayfire is in activity for something I don't now.

How to reproduce:
just zoom in the desktop by using +mouse wheel

Expected behavior:
less gpu and cpu usage (which are almost at zero, especially the gpu usage, when the desktop is not zoomed in).

Screenshots or stacktrace
If applicable, add screenshots to help explain your problem.
If it is a crash, attach the backtrace (or the whole log file), Wayfire will print it in the end of the log file or stdout.
Backtrace with address sanitizer enabled (if possible):

Wayfire version:
0.8.0 (and previouses)

Plugins used in my config file:
plugins =
alpha
animate
autostart
command
decoration
fast-switcher
foreign-toplevel
gtk-shell
idle
move
oswitch
place
resize
shortcuts-inhibit
switcher
wayfire-shell
window-rules
wm-actions
zoom

The issue names no source file, test, or entry point. Start by reproducing the zoom effect with Super+mouse wheel while measuring CPU and GPU usage, then trace the zoom plugin's rendering activity. Done means zooming no longer causes unexpectedly high resource use while preserving the effect.
