3 Displays, Windows on left always move to centre display on restart, how to fix?

[draylax]

I have Asus Gryphon Z97

i7-4790k 

Intel HD 4600 Graphics (IGPU disabled in UEFI) 

Radeon RX580 (MSI Armor OC 8GB)

 

I have 3 LCD

Centre 30" 2560x1600 connected to Top DisplayPort

Right 30"  2560x1600 connected to DVI-D Port

Left 31.5" 2560x1440 connected to bottom HDMI port.

 

I position all my application windows on each display,

on restart all the application windows on the left display are moved onto the centre display leaving it blank.

All applications windows originally on the centre display retain their position, same with the right display, all window positions are retained.

 

With this current Cable connection config from card to LCDs, when I boot the machine the centre LCD displays the verbose code (Clover is set to 0 time out so I skip this) then all screens go black then the centre LCD displays white Apple Logo on black background until the desktop arrives.

 

This is how I want it. 

Unknowingly, if different ports are used for the different LCD's then all hell of randomness breaks loose, the verbose code may display on the left LCD and then the Apple logo displays on the right or centre LCD until desktop ,or other switching variations, there's not much of a reliable pattern to determine which LCD will display verbose and which will display Apple Logo. So it seems beyond user control unless there's some setting the user can set a forced port priority on the graphics card. 

 

I have SwitchResX and have saved the current window application position but it's getting over ridden by some issue in the boot stage that is messing everything up.

 

I have Whatevergreen v1.3.5

Lilu v1.4.0

in EFI/Clover/kexts/Other

 

 

Clover Config:

Graphics Pane:

FB=Orinoco

VRAM=8192

ig-platform-id=0x0d220003

 

Arguments:

-v

keepsyms=1

debug=0x100

shikigva=144

shiki-id=Mac-7BA5B2D9E42DDD94

 

SMBIOS:

Product Name=iMacPro1,1

(This config allows full HWAcceleration on the Radeon HEVC/H264 encode/decode)

 

 

This Restart messing up my window sets is driving me insane, in fact also is the randomness of the boot verbosity display and Apple logo display on the LCD.

 

Anyone have ideas what is issue and if there are fixes for this?
