Visual Flickering, Slow Main Display – iDisplay Review

It now works on high sierra, but there are a couple annoying issues (not unique to this product). The header of the safari window flickers. That is various rectangular shaped blocks (random in size & shape) turn dark gray, then back to light gray... Very irritating... Also, the frame rate on my normal monitor noticeably drops when iDisplay is active... I can state for a fact that these exact issues occurred with a competing product on the app store, so the issue is not unique to iDisplay. I can also attest that whatever the root issue is, I’m able to reproduce these issues on another model mac with another model iOS device, so it’s not a specific hardware issue...
