VMs video drivers rarely have full opengl support. So it's likely that sigil is using the included mesa software implementation of opengl (opengl32sw.dll).
You could try forcing the use of software rendering on your non-vm machines by setting the QT_OPENGL environment variable to "software".
Another independent thing to try is under Sigil's General Settings preferences (Advanced tab), check the Disable GPU Acceleration in QtWebEngine option. I THINK WebEngine is used to display images in the resource tabs.
Does it happen with all image types, or does it tend to be certain ones?
