Hi There,

In this case I am using Impress however this issue may be consistent across all applications.
I have an Intel NUC7i7BNB with Linux Mint Sonya (AKA Ubuntu 16.04)
I have installed the official Intel Driver via the intel-graphics-update-tool.
I believe the Intel driver installs its own PPA version of OpenGL, as per output of glxinfo.

jordg@gold ~/ $ glxinfo | grep "OpenGL"
OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) Iris Plus Graphics 650 (Kaby Lake GT3e) 
OpenGL core profile version string: 4.5 (Core Profile) Mesa 17.3.2 - padoka PPA
OpenGL core profile shading language version string: 4.50
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile
OpenGL core profile extensions:
OpenGL version string: 3.0 Mesa 17.3.2 - padoka PPA
OpenGL shading language version string: 1.30
OpenGL context flags: (none)
OpenGL extensions:
OpenGL ES profile version string: OpenGL ES 3.2 Mesa 17.3.2 - padoka PPA
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.20
OpenGL ES profile extensions:

If I do not use OpenGL, in Tools -> Options -> LibreOffice -> View, the performance is very slow moving objects or changing sheets. With OpenGL the performance is good but with tearing as below.

Thanks
