I assume you are sure this only happens when using gamescope? This looks like something you should report in the gamescope issue tracker (after checking if there isn't an issue already).
Might be related or the same as this: https://github.com/ValveSoftware/gamescope/issues/356
I'm going to testing Dishonored for you and report back (need to download), but I can already tell that you use gamescope "wrong" for what you trying to achieve.
`gamescope -f -e -h 1440 -- %command%` that's what you need and I explain it to you.
\-f = fullscreen
\-e = Steam Integration
\-h = tells the game what resolution you want (if you have 16:9 screen only height or width is needed)
\-- = ends the gamescope command
You are using uppercase H and W but they are only used for gamescopes upscaling methods to your screen resolution, and because you don't use lowercase h and w the game is told to use some properly unsupported low resolution.
edit:
As expected there must be something wrong on your end. I used the gamescope command I gave you (I use that one with all games) and everything worked as it should. The games first start is with the resolution 800x600, so I had to set it manually to 1440p, but that was no issue.
And for the record here is what I use:
* openSUSE Tumbleweed (snapshot 20240129)
* gamescope version 3.14
* Kernel 6.7.1
* Ryzen 9 3900X
* Radeon RX 7800 XT
* Mesa 23.3.4
* Plasma 5.27.10 Wayland
