When making a pixmap exportable, glamor will currently create a temporary
exported pixmap backed by a GBM bo, with the devKind updated to the stride of
the bo. However, when the backing of the exported pixmap is swapped into the
original, the devKind of the original is not updated.
Some GBM bos may get implicitly padded, in which case the devKind of the pixmap
will not match the stride of the backing bo. For example, an 800x600 pixmap will
have a devKind of 3200, but the bo's stride will be 3328. This can cause
corruption with PRIME, when the sink uses the wrong stride to display the shared
pixmap.
This commit changes glamor_make_pixmap_exportable() to update the devKind of the
original pixmap after it swaps exported pixmap's backing into it, keeping
everything consistent.
Fixes issue #1018.

X Server
The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into.
Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders.
For a comprehensive overview of X Server and X Window System, consult the following article: https://en.wikipedia.org/wiki/X_server
All questions regarding this software should be directed at the Xorg mailing list:
