100% CPU core utilization while moving cursor

Hello,

I recently moved from X6 to 2020 and I've noticed strange issue. Moving mouse over Corel UI cause very high CPU core usage - almost 100%. It happens even on fresh start, with no document opened. This doesn't happen to that extend in X6 - it's around 25% at best. Same thing on two different machines, both running Windows 10. I've tried decreasing mouse polling rate and DPI, no avail. Everything is up to date. Clean install doesn't help. Ia this normal behaviour? I'm generally not pleased with overall performance of Corel 2020 comparing to X6.

My specs:

AMD Ryzen 3600/3400G
16 GB RAM
NVMe SSD
Nvidia GeForce 2060 Super
