exa: unset fence pointer on pixmap data release #36

Closed digetx closed 6 years ago

digetx commented 6 years ago

I'm not exactly sure when ModifyPixmapHeader could be invoked, so better to just clear the pointer.

Now, looking at the Xorg code, I'm also not sure whether we should re-allocate BO if modified pixmap is larger than it was before modification. Maybe reallocate behavior, that we had before, was correct.. I haven't spotted any issues with ModifyPixmapHeader, though I don't quite understand it. @kusma maybe you know?

I don't really know much about this, so I don't think I have much useful to chime in with.

Ok
