Hey @aras_p

Apologies for the slow reply. Just to let you know that it seems your bug fix is behaving better on linux. Thanks again for your help!

Thanks @aras_p !! I'll check this out and give some feedback

Interesting, thanks @aras_p for checking.

Yeah, I have a feeling something like this could be happening. I'm still trying to find the root reason why this could. Potentially the CPU flags are…

So currently this is with 4.3.0, so it could be there has been regression. But I did pick it up once with 4.2.1 a few weeks ago. It's strange in that it's seemingly an intermittent problem. And…

Hi @aras_p and @ValZapod

I want to open the issue again. It seems the fix was looking good, however in the last while it seems that the issue comes back intermittently when spinning up new…

So just an update on this @OmarEmaraDev . I've managed to solve it, the issue was actually due to an underlying OpenGL context. It seems in the container was defaulting to llvmpipe which meant…

Ok, I can confirm the same behaviour locally, albeit different speeds due to the hardware being more powerful on my local device. So potentially there is something to do with the gpu interaction…

I will give it a try to confirm! I just don't have a linux base setup, but will try on my windows with WSL2

Big thanks @aras_p :) Glad you also got to play a bit with AWS! Wishing you the best

@aras_p I can confirm the issue is still there with VSE from your .blend setup

@Sean-Devonport ah did not notice your comment wrt AWS. That's a good idea, I can test things like that myself, thanks! (once I figure out how to use AWS, that is :)).

No problem :) If it…

@aras_p Thanks so much. Happy to do a custom build and also if you have any directions for recompiling the ffmpeg libraries with the different instructionset, I'd be happy to try that aswell.

Thanks @aras_p for the fast response.

I can confirm the behaviour is in 4.1, 4.1.1 and 4.2
