External Monitor orientation does not persist after sleep

Looks like the prior thread on this was never answered.

Situation: MacBook Pro (2019) dual external 4K LG monitors in Portrait orientation connected via thunderbolt 3 directly (no HDMI) (USB-C for this who care). After the Mac sleeps, and re-awakes, the monitors are both rotated 180 from the previous setting (yes that means both monitor displays are now upside down). This is a smidge "inconvienient" =8-o.

Solution: None yet that I've seen posted. Apple? Have you a solution?

So I’ve opened a case with Apple support. This problem is now clearly reproducible.

in short, turn on screen saver, allow it to run and then time out and **** off the external displays. the computer enter a sleep state.

Then awaken the computer. The external displays will either a) Rotate the images 180° or b) swap the images on the left and right monitors. To rotate then back 180° the fastest method is to unplug both USB-c monitor cables and plug them back in. Otherwise you can use the monitor configuration settings on the Mac to rotate then again.

as for the contents swapping between the external monitors after sleep, still working on how to reproduce that one.
