[X2Go-User] Web browser performance over X2Go

[Walid MOGHRABI]

Also encountered that (and even stranger things related to video playing with Youtube for example but not limited to it ...). 
Did you try to disable hardware acceleration and smooth scrolling in the advanced preferences ? 


I did and it gaves me better results.

Stefan, thank you. I did not think to restart the browser when I tried to toggle that setting. This is a great improvement! 
Too bad they are deprecating this feature. The video you shared in the link demonstrates exactly my experience. I hope the FF team decides to continue supporting this legacy mode. 
Thanks again for sharing this.

It's still there in the 51.0.a1 nightly build. 

There's a conversation on reddit about it (started by me) and also a bug report:
