Public bug reported:
After the last driver update for my Radeon HD 7750 Im having viewport
problems in Blender when displaying meshes with multiple materials (see
attached screenshot).
This happens both with both the latest version of Blender snap and the direct
download from Blender.org
I also have an older version installed and is having the same problem.
It all worked fine before the driver update.
Just in case these are the last lines from running grep "upgrade "
