Sleep Catalina 10.5.5 - GA Z270X Gaming K5

[haino]

Sleep working 100 percent under High Sierra.

Using same EFI for the two systems.

Problem to sleep in Catalina, mouse pointer stops moving only. Destop still displayed. Mouse-click releases mouse pointer again. See attached files.

Replacing the grafics card with a Sapphire Radeon RX580 8GB solved the problem. thx.
