Public bug reported:
I recently upgraded to ubuntu 20.04 beleiving that it was LTS, but later
found out that it was the development branch. In this version frequent
lags occur while using applications like google chrome. There is
pixelation of the top bar and sometimes the desktop icons are also shown
pixelated while using some application. It happens very frequently , say
every 5 minutes and is very annoying.
