gamescope 3.12.7-1

Unfortunately, Gamescope is affected by an Nvidia driver bug that Josh needs to work around (#948). My recommendation is to use an older version of Gamescope until it gets fixed.
You can revert it on your Arch-based system by grabbing an older package from Arch Linux Archive:
sudo pacman -U https://archive.archlinux.org/packages/g/gamescope/gamescope-3.12.5-1-x86_64.pkg.tar.zst

Yeah I noticed this issue with gamescope-plus package.

Well you are in luck, since May this year, no package of Gamescope have worked for me under Nvidia.
Now to verify it wasn't Gamescope itself being faulty, I have tried the same versions on my laptop that is an all AMD setup with a Vega 3 GPU.
Suffice to say, it runs flawlessly and I can really see why people love Gamescope on there.

I also ran gamescope through Intel iGPU, which worked fine as a workaround until 545.
Hopefully NVK will give us some hope in the future if Nvidia doesn't fix this.

I'm also getting this error on a 3090 on endeavouros. Let me know if I can send any logs or anything to help

Try the 535.43.20 vulkan beta branch, gamescope is working on that branch for me.

[jarrard]

just use gamescope 5.12, easier solution

[jeisom]

Try the 535.43.20 vulkan beta branch, gamescope is working on that branch for me.

Still broke here with Vulkan beta x.x.20. Immediate segfault. 5.12.5 works though.

Yeah, it beta drivers fixed some stuff on 5.13 but some games would outright refuse to launch. 5.12.5 was working yesterday, but now it's not working, no idea what changed so it's a little frustrating

[unhappy-ending]

Another update, 535.43.20 Vulkan beta branch had intense horizontal screen tearing while playing games. I can't recommend it. 545 has major flickering in Chromium based web views which means Steam's overlay, but there isn't the screen tearing issue and Steam can use software rendering to "resolve" the disappearing graphics and flickering issue. Gamescope 5.12.5 is still working fine with 545, so it seems the best thing to do is stick to it until Nvidia resolves all the issues at hand.

[jarrard]

Some of the issues may just be wayland related if your using that (most are these days). Still some rough edges for NVIDIA under Wayland which you need to work around.

[HunterCZ122]

If you guys get crash when launching any Vulkan game, you need to disable Gamescope WSI as a workaround:
ENABLE_GAMESCOPE_WSI=0 gamescope -- %command%
Kinda weird Nvidia didn't backport fix for Vulkan WSI on Wayland.

Still blackscreens games on nvidia and wayland

[thechitowncubs]

Total black or transparent window with nvidia 545

[AlexFolland]

I'm getting permanent freezes in the first minute with gamescope on Nvidia with Nvidia 545.29.06. It's not a black screen, but it's still unplayable.

[thechitowncubs]

I pulled updated git and it works but permanent freeze issue here too

[peacey]

I am having a similar issue with gamescope freezing or having a blank screen when running a game. Using latest gamescope git, latest Nvidia 550 beta driver, and kernel 6.7.2.

The issue manifests slightly differently if running gamescope from within another compositor or standalone.

1. If running gamescope from another compositor (like kwin), the game starts up and video works for a few seconds to a couple minutes then freezes completely (only video freezes, audio remains playing in background so game is still running). The game never unfreezes, can't be exited sanely, and can only be force closed by killing the gamescope session.

2. If running gamescope in its own standalone session, the game starts up in a black window and never updates. The audio can be heard so game is running, but the window remains black forever. Again, only force killing the game or gamescope can close it.

All these tests were done with only the minimal parameters "-W 1920 -H 1080 -f". Issue happens whether HDR is enabled or not.

Sidenote: HDR gaming with Nvidia for the first time with the 550 driver was super cool for a hot minute before the game froze!

As far as I can tell, this issue still persists, specifically trying to fix Fragpunk running in hyprland.
The game starts just fine, and when I try to join a match or go into the range, it works briefly before crashing. Any news on this?
