If you are using and AMD RX series or new card (this could affect older models) there is a driver bug that causes severe Corel Draw 2017 performance issues. I was running AMD Adrenaline 17.12.2 and I tried the latest version 18.1.1 and both rendered Corel Draw 2017 useless. I uninstalled both driver versions and reverted back to the Microsoft update service driver version 17.50.15.01-180112a1-322990. Corel Draw 2017 now opens, edits converts files perfectly fine again.
My system specs:
GA-AX370-GAMING K7
Ryzen 1500X
G.SKILL 16GB DDR 2400 memory - F4-2400C16D-16GFXR
512GB Plextor M.2 M8Pe(G)
GV-RX580AORUS-8GB
Had to go back to 17.7. Driver 18.1 opening saving exporting makes computer sluggish.

17.7 WOW You can see from my post the Microsoft update service driver is 17.50.15.01-180112a1-322990.
