Chrome browser speed and font issue

I have received M64 and i was trying different Ubuntu builds. Normally Ubuntu builds are loading correctly but Chrome browser works very slow. I also see that it does not load fonts and characters comes as box. I’m planning to use M64 in a project where i will run web browser(Like web terminal display) so browser performance is very important. I also can not run youtube videos in browser without flickering. Can you help me how i can over come to this issue?
