Finally got a chance to reboot, and it definitely made a difference with
playing 4k videos.

However, playing two 4k videos at the same time makes both of them slow.

This is on my i7-12700k with 64GB and the Radeon with 4GB:

07:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI]
Ellesmere [Radeon RX 470/480/570/570X/580/580X/590] (rev ef) (prog-if 00
[VGA controller])
        Subsystem: ASRock Incorporation Device 5026
        Flags: bus master, fast devsel, latency 0, IRQ 194
        Memory at 4000000000 (64-bit, prefetchable) [size=4G]
        Memory at 4100000000 (64-bit, prefetchable) [size=2M]
        I/O ports at 3000 [size=256]
        Memory at 82000000 (32-bit, non-prefetchable) [size=256K]
        Expansion ROM at 82040000 [disabled] [size=128K]
        Capabilities: <access denied>
        Kernel driver in use: amdgpu
        Kernel modules: amdgpu

I'm pretty sure I recall playing multiple 4k videos at the same time with
fc37 before this problem started. Do you have any other ideas what could be
causing this jerkiness?

Thanks,
Alex
