Ambiant-MATE could have improved LibreOffice theming

[Yousuf 'Jay' Philips]

Ubuntu Mate 16.04 Beta 1 & 15.10

LibreOffice pulls a particular color reference from the desktop theme and uses it in various places and it seems the particular color it pulls from the default Ambiant-MATE likely isnt set, as LibreOffice is using black in those areas. This doesnt happen with other bundled themes like Blue-Submarine, High Contrast, Menta, Radiant-MATE, TraditionalGreen, and Yuyo. The only other bundled theme where this issue arises is in GreenLaguna.

The attached screenshot has red square around the areas that are affected by this selected color.

I can confirm it the black elements.
But here on my computer there also are some artefacts with checkboxes (checked and unchecked).
The only themes without this problems are Green-submarine, Blue-submarine and the two contrast-themes.

Please see my screenshot.

What about this bug? I installed MATE 1.14 since a couple of days and i thought this problem would be solved.
Ambiant-MATE is my default theme. But this problem is also present with Blue-Submarine.

When i switch on" OpenGL Rendering" in LibreOffice Settings the problem seems to be solved. But LibreOffice lags a little after switch on this setting.

I can confirm this with Ubuntu MATE 16.04, Mate 1.14.1, LibreOffice 5.1.4.2, GeForce 750Ti (driver version 361.42).
However in my case the OpenGL workaround does not work because it causes the application to crash (fortunately it reverts back to normal rendering on the next restart).

This is impossible to fix until LibreOffice fully supports GTK3. Basically LibreOffice is using the menu background colour from the GTK2 theme to colour those elements, and it shouldn't.

If all GTK2 menus are made light then LibreOffice looks correct but then all GTK2 applications look incorrectly themed.

This issue has been submitted to the libreoffice team - https://bugs.documentfoundation.org/show_bug.cgi?id=101671

Ubuntu 16.10 ships LibreOffice that use GTK3+ by default and also carries a vendor patch to theme it. It is therefore now possible to address this issue, and we have :-)
