Red pixel artefacts on Fujifilm X100T @ISO 800

hi there, i'm developing a couple of raw files from a recent project and i'm noticing some red sparks on the shadows, i'm healing them by hand (which is something i dislike tbh) but i want to know if anyone here could steer me into the right path of knowing what is going on with my sensor, thanks a lot!

ps: jpg files also depict the artefacts but in a desaturated way

Run your camera's pixel mapping function if it has one. Permanently hot pixels can be incorporated into the de-bayering algorithm to reduce their appearance in the jpgs. RAW files will the unaffected.

Flaws or damage to the CMOS picture elements will produce the permanent variety while the transients are more common at higher sensor ISO. Ambient radiation levels probably have an effect too.

thanks a lot!
unfortunately, my camera doesn't come with pixel mapping function.
but i did a bit of homework, and learned that this phenomena is somewhat common to happen under heated conditions and precisely above ISO 800.
i'll just keep an eye the next time, thanks again!

Yup, looks like a hot/stuck pixel.
My aging Canon 7D has several after I've used it as a webcam (don't ask!) for about a year.

won't do , but i bet the streaming quality was superb!

Oh yeah, people were pretty amazed. I used it a lot for lecturing during covid, too!
