I just upgraded from 18.04 to 20.04 (LTS). But now I can't play full-screen videos, whether from web browser of even VLC. Whenever I select fullscreen video. It creates "picture in picture" effect in the upper left hand corner, screenshot below.

My machine is a win10 dual boot, Acre Aspire 5. The output of sudo lshw -C video is

UPDATE 1
The seems to be a bug in the 18.04 to 20.04 update that "prevents" the installation of some key drivers / software.
1.) using ubuntu-drivers devices to figure out what driver was missing and (recommended)...
2.) then using sudo ubuntu-drivers autoinstall
Which actually FAILED.... with the following error:

However, I was able to immediately fix it using the same solution to the problem of not being able to install shutter.
The answer is in this post
Once I did this, I was able to finish the installation of the correct nvidia driver, rebooted, and verified that it was installed in "softwatre & updates"....
After all this... SAME PROBLEM... this is definitely an Ubuntu 20.04 bug.. had 18.04 on this machine... no problems. The result of sudo lshw -C video is still display: UNKNOWN
Update 2
I went back and tried ALL of the suggested solutions by @hyttysmyrkky listed below. And NONE of them worked. The result of sudo lshw -C video is ALWAYS display: UNKNOWN . FYI, this includes using the -47 kernel and the 440.100 driver. NONE of the solutions worked, Same picture in picture, fullscreen mode problem. In addition to this error, under 20.04 I had the following problems:
1.) Unable to power off my machine from system menu. Screen goes dark, but the shut-down process would literally just hang no matter how long I waited, finally required a hard shutdown of holding the power button.
2.) The recognition of my intel wifi card was hit or miss at boot time. If failed, I needed to re-boot to in order get wifi working because restarting network-manager had zero effect
3.) on a very annoyingly frequent basis, at boot my I would receive MOK messages (machine owner key) messages asking me to select boot systems even before grub. This would happen no matter how many times I had previously done the same thing.
4.) Often the bios settings would revert to system defaults, completely bypassing grub and loading win10, which created the need to: 1.) re-boot windows in safe mode, 2.) enter bios change "sata settings" to from "RAID with array" to "AHCI", disable fast boot, 3) Log back into Win10 turn off safe mode and re-boot. (i.e. giant waste of time)
I finally "fixed" the problem, by reverting back to 18.04 in which the "manually installed driver" option seems to work perfectly with the nvidia driver. 20.04 is "eye-candy", but I will wait year before attempting to upgrade again. Just switched to the NVIDIA-driver-450-server on 18.04 and it too works perfectly.
UNCLAIMEDindicator inlshwmay be an indicator that a proper driver is not installed for the NVIDIA card. – FedKad Oct 03 '20 at 10:54
