Moin!
I can reproduce with my X270. With -current it does not work and with
6.9 both external monitors run without problems.
Same problem as I had already mentioned here:

Ah, I'd seen your post but was thrown off by the mention of Thunderbolt,
and hadn't noticed that you had also tried with a non-Thunderbolt dock.
Thanks for confirming that it previously worked OK on your X270.
I've been searching for additional reports, and it seems as though the
Intel 4xxx CPU series w/ HD Graphics 4400 might also be impacted. Here
is a user on reddit writing about similar symptoms on a Lenovo T440p:
