Strange Artifacts in HiRes Mode

  1. I have been experimenting with the hi-res mode on my E-M1 Mark II. I have noticed some strange artifacts that appear in several locations in my hi-res shots, both in the JPeg and the 80mb raw images. They are sometimes red and sometimes blue. They only seem to appear in the shadow areas of low light, low ISO, long exposure shots. They do not appear in normal resolution shots under the same conditions. I've attached a couple of 100% crops. These came from a hi-res raw shot with a 75mm lens, at f/8, 8 seconds, 64 ISO. Has anyone else seen anything like this before?
