high cpu load and lag on dual monitor setup

[ZAVO]

We applied the update but notice little change.
We have the following setup:

Lenovo Thinkpad 13
Windows 10 EDU x64 (up to date)

HP Elite USB-C docking station

monitor A: HP Compaq LA2205WG, @ 1680 x 1050, VGA-> HDMI
monitor B: Lenovo Thinkvision, @ 1680 x 1050, VGA-> HDMI

--> monitor A plugged in laptop
--> monitor B plugged in docking station


Monitor A has no delay.
Monitor B has slight (but noticable) delay and CPU load goes way up (80-90%) when moving windows around (fast).

Prior to this beta, we circumvented the problem by lowering the resolution on both monitors.
Eventhough we have few setups with 2 external monitors, we hope this issue can be resolved in the future.

Thank you Zavo,

What is the approximate resolution of that window you are moving?
Can you confirm the CPU is consumed by WUDFHost?

Kind regards,
Alban
