xandr doesnt recognize native 2560x1440p resolution

I have a Radeon 7900xt card on a Wayland gnome install with mesa vulkan-radeon libva-mesa-driver mesa-vdpau drivers installed, I try to configure the resolution on my 2560x1440p @ 360hz monitor with the following commands but it fails:

Re: xandr doesnt recognize native 2560x1440p resolution

on a Wayland gnome install

xrandr & cvt/cvt12 are for X  .
Under wayland they are ran through a bare-boned X called xwayland and can do very little.

You'll have to use gnome tools to check things as wayland doesn't have a counterpart of xrandr .

Thats what I thought, and in Gnome tools it even recognizes the resolution as 2560x1440 @ 360hz, but when I start a game in steam the game's resolution cannot be set past 1456x819 which is also the same resolution set automatically on xrandr.

Steam runs on xwayland - the resolution looks freakish, so this is likely some HiDPI scaling in action? (factor is 1.76. resp 0.57)
