I installed Opera 36 on my linux machines (Fedora 22 Gnome, Mageia 5 Gnome, Ubuntu 15.10 Gnome). All is fine except for the default zoom level which seems to be set to something like 80%. Some web-pages look a bit better with this zoom, but many pages are much worse. I didn't find any way to configure the default zoom neither in the Opera itself, nor with any extensions. How can I do it?
