Having same issue.
Fedora 44, steam installed as rpm, 9070xt.
I'm also having the same issue
CachyOS, latest version
Radeon 7600xt
I solved the issue by switching to Manjaro, my guess is that because Manjaro takes awhile to update it’s more stable maybe?
Same issue, cachyos, 7900XTX + 7800X3D
Similar with nvidia 5080 + ubuntu 26.04 gnome wayland. Managing any menu in the overlay is extremely laggy. 6 seconds to just update the hovering mouse highlight of an achievement.
Strangely enough if I alt+TAB to steam page while overlay is open the steam page lags for a second and then it behaves fast (normal) for a moment and if I come back with the mouse (not leaving the steam page focus, just hovering from one app to the other ) to the overlay is fast for a second and then super slow again.
I made a video to show the behavior of the overlay when I change the focus

@richardegoldstein7-spec can you watch the video and confirm that this is your problem too?
I switched from the latest cachyos kernel to the LTS kernel (6.18.32-1-cachyos-lts) and it's working better (although not perfectly, there's still small stutters when using radial menus and the like) now, this appears to be a kernel regression.
Disabling HW acceleration in interface solves this temporarily, but then big picture mode becomes unusable.

Disabling hardware acceleration didn't fix anything for me, but it sure did make bpm way worse
Same issue here. Not sure when it started and have also tried all the fixes above.
As someone else mentioned switching to 6.18.33-1-cachyos-lts massively improves it. I tried roiling back to 6.19 (non-lts) and it's still laggy. Maybe not as bad but no where near as good as the 6.18 lts.
Same issue with me on my nobara, 7.0.9-200.nobara.fc43.x86_64. Turning hw on and off did nothing. 6700xt 9700x
Did some further testing, and the lag starts with kernel 6.19. I tested vanilla arch kernel 6.18 and 6.18 LTS on my cachyos system and both fine. 6.19.5.arch1-1 lags. And everything since lags as well. Hope that's useful.
Same issue with me on arch. 7.0.10-arch1-1. Rx 6800xt, ryzen 7 5700x
Same issue for me. LTS fixes the issue. Hoping it gets fixed as it’s sad I’m missing out on BORE with my CPU.

It seems like this issue has been caused by a (recent) kernel update, if you want to help fixing this issue, start bisecting kernel updates to find the exact commit that introduced this issue. @eskay993 already did some of this work, maybe start from there.
I was inspired to learn how to bisect, and after some testing I think I found the offending commit.
Tested upstream kernel built with a generic config and no issue at all on any kernel version.
Tested upstream kernel built with the cachyos config and the issue is exactly as described above.
Bisecting then poined to this commit:
e97d7c5165227e6e4423b4a869d7805b01706392 mm: shmem/tmpfs hugepage defaults config choice
Tested upstream kernel with the cachyos config and that commit removed and everything works perfectly on 6.19.5 and 7.0.11.
Tested latest cachyos kernel patched to remove that commit and also works fine.
I tried transparent_hugepage_shmem=never kernel param to see if it can be fixed without a patch, but no luck. I suspect tweaking CONFIG_TRANSPARENT_HUGEPAGE_SHMEM_HUGE_ at build time would solve it.
I'll report to the cachyos as it seems most relevant to them at this point, but leaving here as well in case it's useful.
One more clue, which may be relevant to Valve specifically.
transparent_hugepage_shmem=never has no affect. The default on arch seems to be within_size. but...
transparent_hugepage_tmpfs=never fixes the issue.
So when CONFIG_TRANSPARENT_HUGEPAGE_TMPFS_HUGE_WITHIN_SIZE is enabled at build time, the issue persists. Changing to CONFIG_TRANSPARENT_HUGEPAGE_TMPFS_HUGE_NEVER fixes it.
For anyone who needs a temp solution, add ~transparent_hugepage_tmpfs=never~ transparent_hugepage_tmpfs=advise as a kernel param. Not sure what wider effect this has on general desktop use, so I would consider this a workaround rather than a fix.
EDIT: Changed the temp solution from never to advise for anyone landing here. CachysOS will change this in their conifg, and It's also bene reported to arch, so hopefully future kernel versions won''t have this issue.
Use transparent_hugepage_tmpfs=advise seem to be enough.
Arch Linux also changed the build option to fix this 🎉️
Updated CachyOS and everything seems to be working as intended on xwayland and gamescope

Your system information
Please describe your issue in as much detail as possible:
I am having a continuous and mysterious bug specifically associated with the steam overlay which causes its performance in-game to be simply atrocious. This occurs both in and out of BPM, and is especially bad whenever invoking on-screen virtual menus: pulling up the menu or moving through it's options will cause horrible stuttering in game. The steam overlay itself is very laggy, especially in the controller layout menu. I have tried many different possible fixes, including:
-using gamescope
-using the arch linux zen kernel
-adjusting number of monitors and refresh rates on those monitors
-env STEAM_RUNTIME=1 steam -no-cef-sandbox -cef-force-glx
-disabling and enabling hardware acceleration in the interface settings
-updating all linux systems and drivers via sudo pacman -Syu
-KWIN_DRM_NO_DIRECT_SCANOUT=1
and some other things as well
This is not specifically with using the new steam controller, I have also tested with a dualshock 4 and the same stuttering persists when invoking an onscreen radial menu. This issue does not persist on the steam deck.
