Many games think my native resolution is wrong (lemmings.world)

This is a recent issue, and I don't know what has changed to cause it. There seems to be no rhyme or reason as to which games work and which ones don't. My monitor's resolution is set to 2560 x 1440 in the display settings, but some games don't recognize it.

Of the games I have installed, Subnautica, Dark Souls III, Sekiro, Control, Hades, and Hi-Fi Rush think my native resolution is 1896 x 1067 and they won't let me change it to anything higher than that.

Elden Ring, Ark Survival Ascended, and Returnal detect my resolution correctly and work fine.

This is all from Steam without any custom launch settings, and with and without gamescope. I've tried custom resolution command line options for Subnautica and that hasn't helped either.

I'm running an RX 6700 XT on Nobara with everything currently up to date. I'm not sure when this issue started, but it's recent, probably within the last week or so. I've definitely run Control and Sekiro at the correct resolution before, but in my recent testing they no longer work right.

Does anyone know what could be causing this? Why some games work fine and others don't?

It is because you have two monitors with different scaling, re your reply below. I have the same problem with my 4K and 1440p monitors as well (200% and 150% scaling, respectively). This has been a rather big problem IMO, so much so that I have not really used the scaling that much and instead relied on increasing font size.

The reason why is that games run through Xwayland, and X only has global scaling factor setting and not a per monitor one. Therefore they have to do some weird stuff that I can not adequately explain, but which is the reason for the applications thinking they are on a lower resolution than they really are.

I actually did a benchmark yesterday and it doesn't really seem to matter performance wise (I thought they might both upscale and downscale, but that seems to not be the case from my testing). It is also possible to tinker with gamescope if any games do not display properly.
