Subject: [PATCH 6/9] backends/native: update glyph cache on resume
776610
776610
As mentioned in a previous commit, the proprietary NVIDIA
776610
driver garbles memory on suspend. That behavior, means that
776610
clutter's glyph cache (which is stored in GPU memory) gets
776610
corrupted on suspend.
776610
776610
This commit ensures the glyph cache is blown away when
776610
the logind session becomes active (on VT switch and resume).
