Some sort of buffering issue(?)

The last, some couple of months, 5 to 8(?), when I use this, superb app btw, I get some kind of buffering issue. I can't say that it IS a buffering issue but it seems like it.

Whenever I connect to the server and watch something using mpv it seems to get a 'hick-up' from time to time, like some every 15sec or so, a hick-up of .4 seconds.

The time between them are not the same and I've checked everything I can to narrow it down but got noting so I figured it must be this. My OS is the same as I've used for years on different machines.

My system NOW is: M/B: X870E AORUS ELITE WIFI7 OS: Vanilla Arch with awesomewm CPU: AMD Ryzen 9 9950X 16-Core Processor GPU: Navi 48 [Radeon RX 9070/9070 XT/9070 GRE] [1002:7550] MEM: "/proc/meminfo"; 96397884 kB
