Maybe I really just overlooked it all the time but then again, the issue is gone when i disable VDPAU, no issue with VAAPI (which seems like it's not used because the overlay says it's still software rendered)

AMD doesn't support VAAPI (yet), which is why if you select it you'll only be using software decoding. 

Yeah, I googled for it and found that AMD doesn't support it as of yet, but there's already something on the horizon.

So far I wasn't able to do some tests on my issue, being sick kinda sucks and falling asleep every 30min sucks as well.
But I already made a little plan on where to start testing.
Will report when I'm better and can start testing.
