Low temp screen issue

[Krzych086]

HI Everyone,  I've got brand new Xz and noticed when I use my phone in low temperature environment horizontal  withe see through stripes starts to appear.  The issue is not something I can't live with as it's only visible when the background is white and I pull down the notifications once, so the bottom of the screen goes dim a bit,  but I want to find out does anyone of you have similar issue and maybe some has idea how to fix it.  Can't send it for repair,  coz I unlocked bootloader on a first day ☺️
