Xiaomi Oreo & Android Auto

I have been using a Note 3 pro with android 6, and works perfect with AA, but now, with a Note 6 Pro, AA show half sized, with black stripes up and down, and touch screen does not work correctly.
I have been reading a lot of forums about it and seems that Xiaomi does not have any solution, only wait for Pie !!
All phones with Android Oreo have the same problem. F1, Note 5 pro, Mi 8, Mi 8 lite, Mi 8 SE...
Any other solution ?
It really sucks, my new phone and I can't use with AA.
Same boat as you... Xiaomi Poco F1: black bar without any icons on the car's display, car display flickering some times, and unresponsive phone lock screen until force rebooted... I'm already running a custom Rom (not MIUI) with Android Pie, so Xiaomi's 'wait for Pie' recommendation I'm afraid won't fix the problem until they decide to really look into this issue...

Question Disable DynamicSwitch screen

Investigating the possible causes of stuttering using the 90hz screen, I came across some users of poco x3 (which has a 120hz screen) reporting a similar problem.
As one of the possible solutions, some users decided to disable the device's DynamicSwitch in order to lock it at 90 or 120hz.
Has anyone tested this procedure on poco m3 pro?
a pilot global ota update was released. it seems 90hz now works fine. also the extra memory bug is fixed

Question M3 Pro display panel vendor?

I'll start my question simple: What display panel does the M3 Pro/Note 10 5G have, and does it have issues with image retention?
My old Redmi 5 Plus (vince) has a Tianma panel, and it has a severe image retention problem. Exact reason why I got myself a new M3 Pro. I heard Note 8 users with Tianma panels also have this issue.
I've tried going into CIT under 'Version Info', and I saw the vendor was TRULY or something. I've been searching on the net for a couple of days, yet nothing shows up, other than the alleged company's website.

Question 90hz lag bug - does it occur with your units?
