I use epiphany on debian/bullseye XPS13 laptop with a 4k screen. In gnome, I set the scaling to 200% so that everything does not appear too small. In epiphany, I sometimes get a transient display where the webpage is displayed on the top-left quarter of the window. Then, after a fraction of a second, the webpage is scaled to the entire window. So, I was wondering if this is due to the scaling and if it would possible to scale the display earlier in the process.
