Comment 133 for bug 1872001

I was also running into pretty horrendous graphics perf (with bionic), and fixed it after I did the following (did all at once so not sure which one did it):

- updated to the 5.3.0-51 kernel
- set the java2d option to opengl (from #82) - although I had issues in other apps too
- updated the Xorg server to xserver-xorg-hwe-18.04 (+ other hwe drivers)

My guess is that the last one is what did the trick. Much better for the last couple of days.
