Bug Description
Xwayland refresh rate reported by 'xrandr' is incorrect:
1920x1200 59.88*+
Actually my hardware runs at 59.95Hz, as confirmed by 'weston-info'.
If Xwayland is reporting the wrong frequency to apps via Xrandr then apps and toolkits implementing frame clocks (i.e. not synchronously tied to swap buffers) may animate at the wrong frequency, causing some stuttering and skipped frames.
