Bazzite + Asus Xg17ahpe incompatibility

Hello,
I bought this screen especially for playing on Bazzite SteamOS. Moreover screen works under Windows 11 Pro (currently, i got dual boot) and also it worked on ChimeraOS.

Issue:
A) HDMI only: Screen shutters every few mouse movements/clicks and/or keyboard presses, later on evry movement and lastly even without any input.
B) USB-C only: most of times it shows Bazzite pre launch screen logo (with cricle in center bottom) then black screen, sometimes it opens in Desktop Mode with distortions (nevertheless I got Deck & HTPC Version and it shouldn't o to desktop so easily)
C) HDMI & USB-C it depends on what cable is first as primary monitor and behave as above.

Hardware: Miniforum HX99G - Ryzen 9 6900HX (with igpu), Radeon RX6600M, DDR 5 32GB, NVME1 2TB (Bazzite OS Deck & Home Theater PC Edition), NVME2 (Windows 11 Pro)

Screen: ASUS XG17AHPE - 240Hz 17" 1920x1080 portable monitor with speakers. Screen can be connected thru usb-c (as power delivery + video/audio) or thru HDMI (as video/audio) and can work on its own battery for some time or take power from outlet (usb-c) or directly from pc thru second cable.

May i provide any log to solve this asap?
