Description Clemens Eisserer 2018-02-06 19:08:16 UTC
Description:
Runing LibreOffice 6 with OpenGL drawing enabled, text is not subpixel antialised (ClearType).

The test system was equipped with an AMD GCN gpu and running Fedora Linux 27 (mesa 17.2.4).

Steps to Reproduce:
start libreoffice after enbaling opengl

Actual Results:  
text is only grayscale antialised

Expected Results:
text should be rendered the same (subxpixel AA / cleartype) and consistent with the rest of the system regardless whether OpenGL or XLib is used as backend.


Reproducible: Always


User Profile Reset: No


OpenGL enabled: Yes
