Jumpy graphics problem

Jumping back on Zwift after a break. Using a new laptop: Lenova V145-15AST and the display is really jumpy, Riders flicking every second or so. And certainly not enjoyable.

Also noticed that the bottom third of all bike tyres appear to be embeded in the tarmac!

I wonder if this laptop (AMD A9-9425 RADEON R5, 5 COMPUTE CORES 2C+3G ) is up to the job or maybe some other reason?
