Linux: using spectralizer freezes the broadcasted video

[ethaniel]

I am experiencing this weird bug, that when I have the spectralizer overlay enabled, I can see the video perfectly on my screen, but when watching on Youtube, the video is frozen (no stuttering, just a frame freeze, can last for hours) and I can only hear the audio.

Hiding the spectralizer source "unfreezes" the video immediately on the youtube stream. I rebuilt the obs from source code (fresh download) and still the issue persists.

There is no frame loss on rendering, encoding or network:

Spectralizer v 1.3.4 OBS v. 27.0.0-19-g3887c0906 (64 bits)

I've got 16cores/32threads, 68% idle:

I need a little more info than that, what does the spectralizer config look like? Also add the obs studio log

Weird, on some OBS starts everything is normal (the spectralizer is being shown on the stream). On other starts I get errors in the log (see below) and the stream freezes.

And here are the entries in the log when the problem occures:

Once I hide the Spectralizer source, these errors stop.

When I mean log, I mean the entire log

Sorry, my bad. Here is the full log - https://transfer.sh/GSKS/log.txt (click "download" on top of the page, since it doesn't show the full file)
