Turning on "big text" option from Accessibility preferences on Gnome doesn't have any effect on Wayland

[pacho2]

Hello
I enable "big text" from Accessibility Gnome 3.22 utils on my laptop to try to read better the letters on my FullHD screen.

The problem is that, as you can see in attached screenshot, letters look nice with native GTK apps and also with QT apps when default theming was used, but when I install adwaita-qt5 and get it used with qgnomeplatform, letters are far too big compared with the native apps
I am using adwaita-qt-1.0, qgnomeplatform-0.3, gtk+-3.22 and qt-5.7

Thanks a lot

This could be a duplicate of FedoraQt/QGnomePlatform#24 because "big text" Accessibility setting on Gnome plays with DPI scaling

We're trying to get this fixed and it's actually a pretty big deal to do it right. Qt font scaling seems to work in a different manner than font scaling in GTK+ which makes it hard to convert the font sizes.

I just tested to enable "big text" and on Wayland it didn't seem to have any effect, while on X11 it seems to work correctly.
