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).
