Question Ubuntu: YouTube videos stuttering.

[RoccoMartinello]

Hi to all!
On Ubuntu 18.10 all was ok, but a problem begun.
I am experiencing stuttering of both audio and video watching video onYouTube.
This is more frequent when, with other tabs opened, I select the YouTube tab.
Doing this I see a frame of the video of a preceding moment regard the audio.
At this moment both audio and video start stutter.
It seems to me that this happens even without other tabs opened.
This happens less frequently with other tabs opened but leaving YouTube tab selected.
I have Windows 10 dual boot and this doesn’t happen with Windows, therefore I think the problem is software-related.
I tried to install Ubuntu 19.04 from scratch, but the problem persist.
I use Chrome, but this happens with Firefox too, therefore the problemis not browser-related.
Afterinstalling Ubuntu 19.04 from scratch the problem seems to be less frequent.
SometimesI have some problems watching my webmail (the central frame is not loaded) and enlarging photos full screen on Facebook (loading not complete).These last two problems are small, but may be related to the stuttering mentioned above.
I tried to clear cache, cookies, etc., but the problem persists.
I don’t think the broblem is RAM-related because RAM isn’t full when the problem happens.
The fault is not of my ISP, nor of an incomplete buffer.
My specs:

How can I get rid of this problem?

Have you downloaded the applicable Linux drivers from the nVidia website and run the installation script as root?
