GUI v2 (of Venus OS 3.52) causes huge CPU Load on Opera Browser

Hello. I recently installed Venus v3.52 on my VenusGX to try the new GUI v2 on my computer.

Having the tab with GUI v2 open in Opera internet browser, the GUI uses about 60% CPU Power of my 3.40Ghz Intel Core i5 CPU! In Chrome it is a bit better but still very high.
With GUI v1 it shows only about 3% CPU load. Is there some kind of coding-bug (with the animations)?

Have the same issue, using OS 3.53.

Running Venus OS on RPi4, using dbus-serial

Installed new grafic card driver CPU load is reduced to acceptable level (from 100 to 30%)
