Same trick as in fb: just do a normal GetImage and deal with the
planemask on the CPU if you have to. Since the software fallback hit for
glamor is pretty brutal, this is a much more impressive win for glamor
than it was for fb:
11100.0 87700.0 (7.901) (copy 0xaaaaaaaa) ShmGetImage 10x10 square
9840.0 47800.0 (4.858) (copy 0xaaaaaaaa) ShmGetImage 100x100 square
1550.0 4240.0 (2.735) (copy 0xaaaaaaaa) ShmGetImage 500x500 square
9450.0 78900.0 (8.349) (0xaaaaaaaa) GetImage 10x10 square
6910.0 30900.0 (4.472) (0xaaaaaaaa) GetImage 100x100 square
431.0 2020.0 (4.687) (0xaaaaaaaa) GetImage 500x500 square
Measured with Xephyr -glamor on Skylake GT3e.

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:

All questions regarding this software should be directed at the
