Hello!

After updating to MacOS Mojave, I noticed that MacBook has artefacts while loading. MacBook starts to load then an artefact appears for a second, then loading is going on. By the way, loading becomes a slower than before.
Artefacts are ONLY while loading. No any other graphical issues while working.

Does anyone knows any solution? It’s very irritating situation.

P.S. pics are attached.
