Ultrawide monitor on wayland

Hi all, I wanted to connect ultrawide monitor (LG 29UM58) to my thinkpad t450 (Fedora 30) but I’m unable to set the proper resolution (2560x1080) - in display settings max what can I choose is 1920x1080. When I switch the gnome session to Xorg there is also no option to set proper resolution via display settings but I can do this with xrandr (maybe not the beautiful way but works). My question is how to force resolution in wayland? Was looking for xrandr replacement but without success.

You can try editing it in ~/.config/monitors.xml.

Editing monitors.xml didn’t help. I found on bugzilla similar problem https://bugzilla.redhat.com/show_bug.cgi?id=1314923 - already closed, so I opened new one.
