--- Comment #4 from Zan Dobersek <zan at falconsigh.net> ---
vsynctester is more of a test on performance of the panning animation. Cairo operations there are slow enough to drop the FPS rate.

https://www.displayhz.com/ is a lighter test for achievable refresh rate.

WPE's limit is the refresh rate established by the compositor or the embedding application. GTK's limit is I think a mix between the fallback timer (used in non-AC mode, hard-coded to 60 FPS) and what the toolkit can provide.
