16.04 - Evolution crashes when looking at contacts - Hardware Enablement Stacks (HWE) issue?

For a few weeks Evolution has always crashed.
When I switch to Contacts and double-click on a contact, Evolution crashes and often the whole Ubuntu session (I have to login into Ubuntu again). Sometimes Evolution crashes even when I only click once on a contact to get the overview of the contact. I get this error in the terminal:

$ evolution
(evolution:29482): camel-WARNING **: Failed to initialize NSS SQL
database in sql:/etc/pki/nssdb: NSS error -8126
(evolution:29482): Gdk-ERROR **: The program 'evolution' received an X
Window System error.
This probably reflects a bug in the program.
The error was 'GLXBadDrawable'.
  (Details: serial 9985 error_code 171 request_code 155 (GLX)
minor_code 29)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the GDK_SYNCHRONIZE environment
   variable to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error()
function.)
Trace/breakpoint trap (core dumped)

When I open the same contact with the right-click menu option "Add to Contacts ...", clicking on an email address in an email and then click Edit, there is no crash and I can safely edit the contact. I can also create a new contact, but when I try to edit it from the Contacts, Evolution crashes.

Not long before I noticed the recurrent crashes I followed instructions to opt-in for HWE (Hardware Enablement Stacks):

sudo apt install --install-recommends linux-generic-hwe-16.04 xserver-xorg-hwe-16.04

I did not know much about much about HWE and wanted to have the most up-to-date system.

As I could not find a solution on Launchpad and through the Evolution mailing list, I tried to uninstall the HWE and it worked! No crashes anymore. Here are the instructions for uninstalling the HWE (Hardware Enablement Stacks):
1. Uninstall new X stack:

sudo apt remove xserver-xorg-core-hwe-16.04 xserver-xorg-input-all-hwe-16.04 linux-generic-hwe-16.04 xserver-xorg-video-all-hwe-16.04

You’ll see the command also removes the ubuntu-desktop package. Don’t worry. The following commands will install it back.
2. Then install back the original xserver-xorg via commands:

sudo apt install xserver-xorg-core
sudo apt install ubuntu-desktop xserver-xorg xserver-xorg-video-all xserver-xorg-input-all libgl1-mesa-dri:i386 libgl1-mesa-glx:i386
