In my PC, I can watch youtube videos without any problem. However, they lag so much on fullscreen, that it's basically impossible to watch them. How can I fix this?

You should check your about:gpu
section in Chrome/ium. In older PC's HW Acceleration is disabled by default and you only can enable it by overriding the settings in the about:flags
.
- Open the
about:flags
in your address bar - Look for Override software redendering list
- Click "Enable"
- Restart Chrome/ium
Had the same problem.
Then I realised Chrome already Flash player built in.
I had also installed the Flash player manually so they were apparently interfering with each other. I just disabled the built in Flash in Chrome and voilla. No lag anymore in full screen.
Hope it helps someone.
This happens to me as well, specially on my older PC, if I watch a youtube video in fullscreen, it lags. What I usually do is to stretch the screen, but not to fullsize or I play it on VLC Player, where it does not lag anymore in full-screen.
To play a Youtube video on VLC Player, copy the address (if you are using secure "https" connection, remove the "s", make sure the link is http://www.youtube.com/watch). Then go to File -> Open Network Stream and paste in the main YouTube URL for a video.
Unfortunatelly this only works with youtube videos for me, Vimeo videos don't play on VLC.
I have solved using youtube HTML5 video player.
You can enable HTML5 video player using the following page: http://www.youtube.com/html5
Now videos are fast and the laf was gone. I have tested it on Chrome.

I disagree with Joren -- the questioner asked about YouTube, not Flash. Google has been moving more and more of their videos to be HTML5-player compatible. Also Adobe has dropped linux support for their Flash player, so it has only received security patches for several years now. Feb 3, 2015 at 22:26
Tried turning down the resolution on the player? Normally, it will automatically up it when you go to fullscreen.
Other than that non-fix, all I can do is feel with you. If internet is running already, then the drivers are at the best they can be. I've found that Ubuntu is just slower than Windows when it comes to wireless Internet.
Not long time ago there was extension for Firefox named Flash-Aid but it's deleted now. Try to find some similar extension/software.
My cable company (Time Warner Cable in the US) throttles youtube. I blocked the IP addresses associated with the throttling (206.111.0.0/16)
iptables -I FORWARD -s 192.168.1.0/24 -d 206.111.0.0/16 -j REJECT
with sudo
(where 192.168.1.0/24 is my LAN subnet).
See the (reddit source) in order to find out what IP addresses are doing the throttling.

Today I struggled with the same question, and I managed to fix it. What I did was, I browsed to the file /etc/adobe/mms.cfg
(if it doesn't exist, create it) and I added the line OverrideGPUValidation=true
to it.
I then restarted my computer and the lag was gone, both on Firefox and Chrome. No 3rd party applications needed.

@Sergei I don't remember. I left Ubuntu for Arch and am now running lag-less.– JeroenJan 20, 2016 at 19:16
For me, changing from the AMD fglrx to the xserver-xorg-video-ati driver in driver management helped.
Unfortunately other software doesn't like xserver-xorg so meanwhile I am using rekonq or konqueror which seems not to be lagging.
Some people have had success with this:
I thought I'd let Ubuntu use more cache... Try this:
(In the terminal)
sudo gedit /etc/apt/apt.conf.d/70debconf
Then put this code:
APT::Cache-Limit "100000000";
on that file and then save it
Next type this code on your terminal
sudo apt-get clean && sudo apt-get update --fix-missing
and you won’t find apt cache limit again in the next time.
