I suppose you should send your current systeminformation details too (command: systeminformation). The most problems come from old graphics card drivers. Is your graphic card driver up-to-date?

Unfortunately, I don’t have this iMac around to test on to see if we can reproduce it. We have seen this sort of thing with older cards and the AMD drivers for on macOS are …disappointing. That said, we have seen some improvement to some drivers in Mojave. I would love to hear if you are still experiencing this in Mojave (10.14.1) or not.
I’m having the same problem yes. I own an iMac of Mid 2011 running High Sierra (Mojave not possible).
I’m guessing this problem is due to the older graphic card yes. Any updates on this?
