Purple pink texture only when they appear or disappear

[Pazurko]

At the end of post i' ll link video that explains it perfectly.

Dunno what happened.
Pc temp is fine, under 65C° for gpu and cpu.
never happened before and in last 3 months i played a lot and never made update-installed anything, just used pc like a console.
turn on, play , turn off
so it's not overclock (i tried also stock),
it's not drivers (to be sure i clean removed, then reinstalle, then upgraded)
it's not hdd (reinstalled to ssd)
should not be faulty files (removed all, even saved games, then reinstalled and started a new game from 0)
should not be settings (tried all defalut combination from low to ultra, no changes)

really cannot understand

i5 3570k (both stock and overclock) temp 64c°
ram 8gb stock
rx 5804gb stock temp 62-65 c°

here link at video where u can clearly see the texture problem: purple pink texture

How about checking the file integrity? If you are on steam version, just go to the game's properties (from steam). There should an option to verify the game files under the local files tab. It will redownload and replace any missing or edited files in your games folder.
