I'm running a MacBook Pro 13,2 with 17A264c. I've got a CalDigit Thunderbolt dock connected (via the ThunderBolt 2 - 3 adapter.) Connected to the dock I have an Apple ThunderBolt display and a Dell 24" display (connected via HDMI and rotated to Portrait.). What I'm finding is that whenever the machine is locked (either via Screen Saver or Screen Sleep) the Dell monitor comes back in landscape mode -- sort of. Although the content on the monitor shows in landscape, the Rotation options in the Displays preferences still show as rotated to 90 degrees. Mouse interfaces also seem to be confused -- I have to click as if the dialog box were actually showing correctly, rather than clicking on the rotation drop-down as it shows on the screen. I then have to switch the display to 0 degrees, and then back again to 90 degrees, before it shows content properly. A reboot will generally fix the issue, but disconnecting and reconnecting the monitor will not. Anyone else have similar issues?
