[Bug 101976] glmark2 random blank or background only screen freeze over mesa3d 17.1 and 17.3 with radeon rx550 AMD POLARIS12

https://bugs.freedesktop.org/show_bug.cgi?id=101976

--- Comment #7 from Pablo Estigarribia pablodav@gmail.com --- I have tried now two more combinations (in /etc/environment to stabilize gnome session):

MESA_GL_VERSION_OVERRIDE=3.0 MESA_GL_VERSION_OVERRIDE=3.1

Up to GL 3.0, everything works fine and stable, glmark2 and gnome session.

With 3.1 or any other higher glmark2 shows only black content on the window opened when I use MESA_GL_VERSION_OVERRIDE=3.1 glmark2 in same session that I openned using /etc/environment.

If I change to:

MESA_GL_VERSION_OVERRIDE=3.1 in /etc/environment, then also gnome session (after login in gdm) got "gdm background" with screen freezed video.
