Question Sudden burn in like effect on LG C2 (used as monitor).

[Titanoca]

Hello,
2 Days ago, I suddenly noticed something like yellow patch at top of my LG C2 screen . Looks like a faint firefox taskbar to me but it wasn't even there until 2 days ago and im pretty sure i didn't leave me firefox open for dozen of hours to get a burn in. So that really took my off guard and pixel cleaning function didn't help either.
So is this like a permanent thing or is there any chance it'll fix itself overtime ?

usually such thing can be cleaned by pixel cleaning
send the TV intos standby, wait for 1hour and try again

use a white image instead of a white window

Yeah, taskbars are the enemies of OLEDs. It's likely still fixable (use the pixel cleaner once a day) as it's probably still just temporary retention rather then actual burn in, but when possible use fullscreen on your browser (F11) for exactly this reason (also: Dark Mode is highly recommended for OLEDs).

It automatically runs pixel cleaning while on standby and I ran it manually twice but read thats not a good thing. I guess i have to live with it for the time being hoping in clears up over time. I still can't remember when i left FF running for ours. I'm usually quite careful . Darn it /
