I tried to use both kernels in my Latitude 5440: linux-image-6.8.0-51-generic linux-image-6.11.0-1010-oem
Both have the flickering problem. The option intel_iommu=igfx_off make the flickering less often but do not solve the problem. intel_idle.max_cstate=2 i915.enable_dc=0 make it worse. lspci 0000:00:00.0 Host bridge: Intel Corporation
