Similar bug fixes (see https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1958191) are not working for my machine. I have used mainline to check kernels 5.15.48, 5.15.50, 5.17 and now 5.18.2.
I have tried updating /etc/default/grub with the following but Desktop icon flickering persits.
i915.enable_dc=0 intel_idle.max_cstate=2
or
i915.enable_dc=0 intel_idle.max_cstate=4
or
i915.enable_psr=0
