Zoom error with wayland fractional scaling on hidpi screen
On my laptop i had to enable : gsettings set org.gnome.mutter experimental-features "['scale-monitor-framebuffer']"
to have a usable gnome (125%)
The problem is with this settings loupe do not show picture full screen show the picture more little than it actually is and i need to manually zoom to have the picture full screen).
The very same picture on the same os, same version, show normally on another device without fractional scaling enabled.
This problem do not happen on eog, witch lead me to a issue in loupe.
