While this topic is related to a Plugable dock, the Thunderbolt implementation
is having some issues for AMD GPUs where display EDIDs can't be read
(https://gitlab.freedesktop.org/drm/amd/-/issues/3050). This latest patch
appears to have helped that issue, as my TB3 Lenovo dock on a Framework 16
with an AMD 7840HS CPU is now able to use its display outputs at the correct
resolutions. I'll be testing with addition TB docks I have access to in the
near future as well.
