For around 1 week so far I've noticed screen tears and other graphical glitches.

I have only noticed them while browsing (in Chrome and Firefox), either while watching streams in flash or html5 format (Netflix, YouTube, twitch, even gifs) or scrolling through a big screen of text or images.

Here are some examples of the glitches I see:

screen drawn with bad horizonal alignment in one place

This is really annoying, since it is constant and is very distracting.

The issue started on Ubuntu 16.04, and I did a fresh reinstall of Ubuntu 17.04 thinking this would solve it, but it didn't.

Currently I am running Ubuntu 17.04 64-bit version on an old Dell Studio 17. This is the gpu info:

lspci | grep VGA
02:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV730/M96 [Mobility Radeon HD 4650/5165]

I have tried 4 different kernel versions and the issue persists:

  1. 4.6.3
  2. 4.10.0
  3. 4.11.12
  4. 4.12.3

I don't know what to do to fix this, can you guys help me figure this out?

Install Compizconfig Settings Manager

sudo apt install compizconfig-settings-manager

In there, go to:

General -> Composite -> Unredirect Match

and add Google-chrome to the list. Be careful with CCSM - it's very powerful.
