when displaying graphics, the system freezes on 20.04

Installed ubuntu 20.04
Integrated intel graphics. When displaying flash in the browser or displaying video in zoom, the system freezes. Only a full reboot helps. The problem started appearing only in version 20.04. At 18.04 on the same hardware, everything was normal.
I think the problem is in the video card drivers.
