Since this is on Intel it is more likely a driver issue you can report here: https://gitlab.freedesktop.org/mesa/mesa/-/issues. It would probably help to explain exactly how to reproduce the problem in game for someone that knows nothing about it.
Thanks for the hint regarding Mesa. I actually found an existing issue that looks very much like mine: https://gitlab.freedesktop.org/mesa/mesa/-/issues/12555

I hope I am at the right place here.
I encounter red pixelated circles that show up sometimes around some items one can interact with. In the case of the screenshot, a terminal and hologram.
Disabling Bloom in the settings removes the glow. Every other setting doesn't seem to affect that rendering artifact.
