Toggle “fractional scaling” and select 125% and 'Apply' the screen start
blinking and part of it is full of noise. To have screen again clean I
unchecked "fractional scaling” selected 'scale 200%' and then again
'scale 100%'

Title:
Fractional scaling switch doesn't work in Wayland sessions
Status in gnome-control-center package in Ubuntu:
Fix Released
Bug description:
Hitting the “fractional scaling” toggle in the “Screen Display” tab in
gnome-control-centre page doesn't work - although the toggle changes
to the “enabled” state there's no visible effect, and if I switch to a
different page (or close g-c-c) and then switch back (or reopen g-c-c)
then the toggle is back in the disabled state.
Running from the command line, I see;
(gnome-control-center:171131): display-cc-panel-WARNING **: 13:34:19.407: no
sunset data, using 16.00
