OBS Studio flickering using newer kernels?

[reinheaven]

Hi,

I reinstalled Manjaro yesterday and my OBS Studio flickers pretty badly as soon as something is moving on the screen that’s being recorded.

Trying different Compositor Vsync settings didn’t do anything. Changing from OpenGL to XRender solved it, but causes bad screen tearing (when moving windows etc.) on the other hand. And I’m pretty sure I didn’t use XRender before.

Someone on reddit suggested uninstalling video-linux driver. Didn’t try this yet because I just set up the system and barely changed any settings, so I am a bit suspicious.

The problem doesn’t occur when I’m using kernel 5.4.135-1, though. Tried 5.10.53-1 and 5.13.5-1 (which I was using on the old installation) but it’s only working with the older one.

Anyone have a clue?

Thanks a lot and have a great weekend!

When using a rolling distro like Manjaro, kernel management becomes a thing, so if it works on 5.4, then keep that kernel and if you definitely need 5.10, get the latest one from Kernel.org, compile it yourself and file a bug upstream if you still run into an issue.

If that would seem arse-backwards to you, please read this:

Difficulty: ☆☆☆☆☆ Remember when you installed your very first Windows, added bells and whistles and then couldn’t see the trees for the wood any more and had to re-install? Well, you’re in the same situation now: You’re a N00b again! Embrace it! I know right now you’re thinking:

Thanks for your advice.

I’d prefer using Kernel 5.13 because everything (but OBS) works perfectly. Strangely enough, I have problems with both LTS kernels. 5.14 does some weird things on my dual monitor setup and 5.10 destroys my SDDM.

Since I also used the latest kernel on the old installation and OBS was working flawlessly, I thought it must be a setting.
