Additional context

Without pinning kernel version to 6.1 it's all good (kernel 6.6)

Hydra: https://hydra.nixos.org/job/nixos/trunk-combined/nixpkgs.linuxKernel.packages.linux_6_1.evdi.x86_64-linux

Started after update to 1.14.6 and looking at changes: https://github.com/DisplayLink/evdi/compare/v1.14.5...v1.14.6 This should be the one: https://github.com/DisplayLink/evdi/pull/467

Looking at branch list here: https://github.com/torvalds/linux/commit/9877d8f6bc374912b08dfe862cddbb78b395a5ef it does not appear to be included in 6.1, even in current 6.1.111: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/include/drm/drm_fb_helper.h?h=v6.1.111&id=e526b12bf9169887f8cfe5afed2b10e56bdca4c3#n132 So it seems to be an upstream evdi issue.
