I also am experiencing this issue, reported it to https://bugs.launchpad.net/bugs/2043905
in the Ubuntu forums, the piece I didn't report there is that I also tried the ubuntu built 6.6 Rc4 generic 64-bit beta kernel and it was also the same problem with that 6.6 kernel... so this may also effect 6.6 as well as the 6.5 kernels.
My system is
CPU: AMD Ryzen 5600X
MB: MSI MPG Gaming Plus (Bios 7C56v1F dated 12 Oct 2023)
Ram: 64 Gig 3200 ddr4
GPU: AMD Radeon RX6600
