Operating System Info

Other OS

Flatpak/Fedora Atomic/Bluefin 44.20260512

OBS Studio Version

32.1.2

OBS Studio Version (Other)

No response

OBS Studio Log URL

I couldn't launch OBS to upload one.

OBS Studio Crash Log URL

I couldn't launch OBS to upload one.

Expected Behavior

OBS crashes with no recovery. Crashes are linked to the obs-nvenc-test process and laptop NVIDIA GPUs. No plugins/extensions and on a vanilla configuration.

Current Behavior

Crashes with no recovery. obs-nvenc-test and all OBS processes create a memory leak and halt system shutdown; the system must be forced off.

Steps to Reproduce

1. Have discrete NVIDIA GPU (mine is a 4060U)
2. Use Fedora 44 (either Workstation/GNOME or KDE)
3. Open OBS.

Anything else we should know?

The Arch Linux build works in a Distrobox, but this is a D20 when it works and hate using it.

Seeing the same thing here. Are you using multiple monitors? I noticed OBS does launch when the system is rebooted without the second monitor attached, but will fail to launch when it IS attached (which is needed here).

Specs:

• OBS: 32.1.2
• OS: Linux Mint 22.3 / kernel 6.17
• CPU: Intel i9-14900HX
• GPU: Nvidia GTX 4060 / driver nvidia-595-open

I don't think that's related. I tried the same thing and it's still not working.

[Shoegzer]

Fair enough, though I do think it's the same issue even if we have different outcomes. Other than the multi-monitor test we're both seeing exactly the same thing, with a crash at obs-nvenc-test. There's clearly a problem with OBS, at least the flatpak.

I don't think so. I have the same issue with Tuba, which fails to launch with GPU acceleration and I'm also having issues shutting down the Steam Flatpak. However, games play fine (I did Death Stranding in Heroic) and DaVinci Resolve is still working. This seems like an issue tied to the 525.71 drivers.

[Shoegzer]

I think you mean the 595.71 drivers? In which case given what you say about Tuba it's possibly related but then, why did you open an issue report on it here if it's not the OBS team's problem to solve? Also, have you been able to test against a different driver to confirm your theory? I will too when I have a chance, just haven't yet.
