Fix low FPS of WebGL in Chrome, in Ubuntu

I've had this problem for a while, Google Chrome seems to lower the FPS of WebGL content / games to 60 FPS on a dual monitor setup, even if my main monitor uses 144Hz !

Well, here is what I think is happening: chrome seems to use the first monitor as a reference to determine the desired FPS of WebGL contents. Now, that does not mean the "primary display" setting, I am talking about the actual numbers you can see in Settings > Screen Display, those numbers :

Display settings

They are assigned by the actual firmware, and so far the only way I've found to change them is to swap display cables on the back of my GPU !

So basically, if your dual monitor setup contains a monitor that is 60Hz, make sure it's not the monitor with number 1 assigned, swap cables until your best monitor is 1, then the problem should be fixed !
