Unable to capture any window using nvidia prime

[arazadaz]

Describe the bug I can not capture any vulkan or openGL application with obs-vkcapture currently. It's just black. It doesn't even show up in obs unless I add the environmental variable OBS_VKCAPTURE_GLVULKAN=1. This used to all work fine. I blame Nvidia, but perhaps you can help me solve this.

It doesn't matter if I run obs on the igpu or nvidia gpu with prime. Same result.

Screenshots or video If applicable, add screenshots or video to help explain your problem.

System (please complete the following information):

• OS: Arch Linux
• GPU: Gtx 1660 ti
• Mesa version:
• obs-vkcapture version: 1.4.2.1

Please also post game log.

Also probably duplicate of #157

I don't think so. I saw that one before making posting this issue. He got his working by running obs on the same gpu as the game. That solution doesn't work for me. He also had a very buggy output in his broken scenario where as my output is just a black box.

Please also post game log.

Is there any game in particular you'd like to to post a log for. Proton games work? How about glxgears?

Anything that doesn't work. So if glxgears doesn't work, please post it.

Is this only OpenGL applications, or do you have the same issue with Vulkan too?

[Sorrydough]

I'm having this issue too now with an AMD 5700XT. It was working in the past, it's just randomly stopped working. In the terminal when I run vkcube it says that it successfully starts vulkan capture. In my OBS scene when I hover over the vkcapture source it shows an outline of the window's resolution. It's just black though. I have no errors or whatever.

This behavior occurs on both wayland and X11. I only have one GPU in my system, not even an iGPU. I'm also on Arch linux. I have this problem with every application.

Please open new issue and post logs.

try starting obs with prime-run too? that fixed my issue

[Kimiblock]

Well I don't need to use prime-run obs to capture GTAV, NieR running on my discrete graphics card. I'm on Arch Linux, with NVIDIA driver version 535.113.01-1 (545 breaks a lot of things for me)
