Best lead I have is that when this happens, top shows kworker/u64:78-events_unbound as the CPU hog during the event.

This happens in Firefox, VLC and Totem. Booting from any 6.2 kernel resolves the situation, and going back to 6.5 reintroduces the issue every time. My system is running 22.04 and consists of a B450 Chipset, a Ryzen 5600x and a Radeon RX 6600 GPU. I am running Wayland. Disabling OpenGL output and going to X11 xcb in VLC prevents the freeze, and disabling HW acceleration in Firefox does the same. I am wondering therefore if this is an issue with the GPU driver in this kernel.
