I'll read it in a moment, since I love architectural deep dives. But question first:
Do you have Patreon or Discord at least? That was TL;DR, I decided to spare you rest and will put it in reply so that people are less assaulted by my off-topic ramblings.

I have an issue with my Framework 16 and it's related to iGPU. I found out that all chips (7840 and 7940) having this iGPU (and possibly also their newer iterations) have the same issues regarding encoding and decoding. Some of it was fixed, some of it's effects can be lessened by choosing "correct" BIOS settings and Performance mode, some applications have workarounds etc. (so it doesn't look like it's 100% AMD drivers fault). But given that it's now been unsolved for over a year I'm starting to suspect that there is some architectural issue, which "could" be fixed using microcode, but possibly with some penalty big enough that AMD doesn't consider it worth it?
IDK - and before someone calls me an NVIDIA or Intel fanboy, my last NVIDIA card was on AGP port and my last Intel CPU that I bought was Pentium II. And I never had issues with AMD cards or CPU's. Even those that were widely reported. But sadly all I can do now is talk on reddit and AMD forum and no-one there is capable of even suggesting how to benchmark (likely micro-benchmark) it and maybe try to find the root cause and hopefully some more permanent workaround.
For now I'm stuck recording screen with OBS, using CPU (OpenGL workaround has it's issues as well) - otherwise any video I record will at best freeze after approx. 2 minutes of recording.
I know there is an "upgrade to paid" option for this substack - and honestly if price isn't ridiculous, I will get on that train maybe even before new year and definitely after. But it would be great to have some communication, because then I would know what programs to run to maybe a bit narrow it down.
And yes, some people say that the problem is fixed.... however first of all it requires turning off many features and second it only decreases chances of that occurring. Sadly it's been 20 years since I've done some serious architecture analysis myself and I can't program (which was my Achilles heel since forever). If I could I would do full investigation myself. Even to only understand better challenges of designing APU's and such.

Yes, there's a Discord (https://discord.gg/fcGB7efq)

OK. Now back to reading.
I have 7840HS in my xiaomi laptop and recording with AMD VCN hasn't been an issue sooo
