As mentioned in the Peppermint 5 Release Notes:-

Quote from: Release Notes
The browsers Chromium and Chrome have recently moved to a new graphics engine called "Aura" that can cause some visual anomalies on the desktop when used in combination with certain hardware. Installing an earlier version of either Chromium or Chrome corrects this.

ONLY follow these instructions if you're getting weird graphics glitches in either of the Chromium or Chrome web browsers

Before we get to downgrading, there is an easier option that works for most people .. but you'll loose desktop effects such as drop shadows, transparency, and compositing .. but if you're OK with that, go to:-

menu > Preferences > Peppermint Control Center > Desktop Effects (tab)

and remove the tick from "Enable Desktop Effects" .. now restart Chromium/Chrome

If that didn't work, or you'd like to keep desktop effects, you'll need to downgrade Chromium and/or Chrome to non-Aura versions .. so re-enable desktop effects and read on...

In the following post I'll explain how to downgrade Chrome first as it's easier than the pre-installed Chromium .. then in the next posting I'll explain how to downgrade Chromium (further down the page).

To downgrade the Chrome web browser -

Open a terminal (Ctrl+Alt+T) and run this command to remove any previously installed version of Chrome:
Code: [Select]
sudo apt-get remove --purge google-chrome*
(don't worry if that command fails, it just means you haven't already installed a previous version)

Now download ONE of these 2 files depending on whether you're running 32bit or 64bit Peppermint 5

32bit:
http://mirror.pcbeta.com/google/chrome/deb/pool/main/g/google-chrome-stable/google-chrome-stable_34.0.1847.137-1_i386.deb

64bit:
http://mirror.pcbeta.com/google/chrome/deb/pool/main/g/google-chrome-stable/google-chrome-stable_34.0.1847.137-1_amd64.deb

Once you have downloaded the file, double-click it to install, then click the "Install" button.

You'll then find Chrome in the menus at:-

menu > Internet > Google Chrome

Fire it up, and go to
chrome://version/
and make sure it says you're running version 34.0.1847.137

If it does .. run this command to stop the software updater from updating it in the future:
Code: [Select]
sudo echo "google-chrome-stable hold" | sudo dpkg --set-selections



To UNDO:-
Take the package off hold with:
Code: [Select]
sudo echo "google-chrome-stable install" | sudo dpkg --set-selections
now uninstall Chrome with:
Code: [Select]
sudo apt-get remove google-chrome*
then download Chrome from the official website:
http://www.google.com/chrome/browser/
and install it in the normal way

To downgrade the installed Chromium web browser -

OK, I've created a PPA with the earlier non-aura version of Chromium (31) to ease installation as much as possible.

To install it you'll need to add the PPA, update the package cache,  install the older version, and rename your original chromium profile directory (as the old version cannot load the new profile).

Open a terminal (Ctrl+Alt+T) and run these commands in sequence:
Code: [Select]
sudo add-apt-repository ppa:mark-pcnetspec/chromium-31
then
Code: [Select]
sudo apt-get update
then
Code: [Select]
sudo apt-get install chromium-browser=31.0.1650.57-0ubuntu1 chromium-browser-l10n=31.0.1650.57-0ubuntu1 chromium-codecs-ffmpeg-extra=31.0.1650.57-0ubuntu1
Now MAKE SURE Chromium is CLOSED, and run:
Code: [Select]
mv -v ~/.config/chromium ~/.config/chromium-original
to rename the profile directory.

Finally make sure the pepperflash plugin is updated:
Code: [Select]
sudo update-pepperflashplugin-nonfree --install

Now fire up Chromium, and go to
chrome://version/
and make sure it says you're running version  31.0.1650.57



To UNDO:-

To go back to the default (with chromium closed) run:
Code: [Select]
sudo apt-get install ppa-purge
then
Code: [Select]
sudo apt-get update
then
Code: [Select]
sudo ppa-purge ppa:mark-pcnetspec/chromium-31
then
Code: [Select]
mv -v ~/.config/chromium ~/.config/chromium-31
then
Code: [Select]
mv -v ~/.config/chromium-original ~/.config/chromium
now fire up Chromium and check it's the latest version.
