Recent libseccomp update killed Steam Proton

Not sure if it should go into bug reports or what, but i want to document it in case someone is trying to google it.

After a routine update all games on Steam started to run extremely slowly or fail to launch at all.

Downgrading all of it fixed things, and after much back and forth i narrowed it down to libseccomp-2.5.3-3 updating to libseccomp-2.5.4-1

With older one everything runs fine, with newer one all Steam games consume 100% CPU and either fail to launch or run as if the CPU is 100 times slower than it should be.

At the same time non-steam games and similar programs run just fine.

Another note is that Proton 6 seem to work fine (at it's usual slowness),  while Proton 7 and experimental are the ones affected.

Relevant packages:

intel-compute-runtime 22.16.22992-1
intel-media-driver 22.3.1-1
lib32-libva 2.13.0-1
lib32-libva-intel-driver 2.4.1-1
lib32-libvdpau 1.4-2
lib32-vulkan-icd-loader 1.3.208-1
lib32-vulkan-intel 22.0.2-1
libva 2.14.0-1
libva-utils 2.14.0-1
libvdpau 1.5-1
mesa 22.0.2-1
vulkan-headers 1:1.3.211-1
vulkan-icd-loader 1.3.208-1
vulkan-intel 22.0.2-1
xf86-video-intel 1:2.99.917+916+g31486f40-2

CPU is i7-1195G7 with Iris Xe Graphics integrated GPU, in case that is relevant.
