Bought an Azulle Inspire for my dad with an i3-7100U and 4K playback is choppy in Kodi. Running Linux Mint 18.3. Any tips for how to fix it?

To receive meaningful assistance you will need to provide a full debug log.

The instructions are here... debug log (wiki)

If you are using the Basic Method, then ensure the following is applied...
1.Enable debugging in Settings>System Settings>Logging,
2.Restart Kodi
3.Replicate the problem.

If you are using the Advanced Method ensure you have correctly created and applied the advancedsettings.xml file.

In both instances, you should see the word DEBUG throughout the log.

Note: Full logs only. No partial or redacted logs
Do NOT post your logs directly into the forum. Always use a paste site like pastebin.com. Post the link to your pasted log in the forum

Use Kodi v18 - there is no hevc 10 bit support for kodi version 17.x on Linux.

DISCLAIMER: I take no responsibility for what you do on your own system.  This is what worked for me.

Add unstable Kodi repository and upgrade to Kodi 18

Code:

sudo add-apt-repository ppa:team-xbmc/unstable
sudo apt-get update
sudo apt-get install kodi

Upgrade Linux kernel to Linux 4.15.0-13-generic

Code:

sudo apt-get install linux-image-4.15.0-13-generic

Add apt-key to download intel-linux-graphics-installer in Mint

Code:

wget --no-check-certificate https://download.01.org/gfx/RPM-GPG-GROUP-KEY-ilg
sudo apt-key add RPM-GPG-GROUP-KEY-ilg

Fake lsb-release to report Ubuntu so the installer works.

Code:

sudo vi /etc/lsb-release

 

Code:

#DISTRIB_ID=LinuxMint
#DISTRIB_RELEASE=18.3
#DISTRIB_CODENAME=sylvia
#DISTRIB_DESCRIPTION="Linux Mint 18.3 Sylvia"
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=16.04
DISTRIB_CODENAME=xenial
DISTRIB_DESCRIPTION="Ubuntu 16.04 LTS"

Download and install updated 64-bit libpackagekit-glib2-18 .deb file required by intel-linux-graphics-installer

Code:

wget http://security.ubuntu.com/ubuntu/pool/main/p/packagekit/libpackagekit-glib2-18_1.1.5-2ubuntu1_amd64.deb
sudo dpkg -i libpackagekit-glib2-18_1.1.5-2ubuntu1_amd64.deb

Download, install, and run intel-linux-graphics-installer

Code:

wget -O intel64.deb https://download.01.org/gfx/ubuntu/16.10/main/pool/main/i/intel-graphics-update-tool/intel-graphics-update-tool_2.0.4_amd64.deb
sudo dpkg -i intel64.deb
sudo intel-linux-graphics-installer

Reboot

Code:

sudo reboot

Revert lsb-release changes

Code:

sudo vi /etc/lsb-release

 

Code:

DISTRIB_ID=LinuxMint
DISTRIB_RELEASE=18.3
DISTRIB_CODENAME=sylvia
DISTRIB_DESCRIPTION="Linux Mint 18.3 Sylvia"

Update: So this got one of my 4K movies running smoothly, but another shows mostly bright green with the image barely visible.

Debug Logs:

Movie That Doesn't Work
Movie That Works

One difference I noticed was that the one that works uses ATEME Titan File 3.8.3 (4.8.3.0) and the one that doesn't uses ATEME Titan File 3.8.12 (4.8.12.0).

I told you above your issue. Disable passthrough, update your VAAPI drivers to wsnipex vaapi repository.

Edit: I am confused. From your log both are working the same ...
