Something's amiss in the graphics support for Linux, sometime after key77b

[nosuchtim]

A report from [email protected] - "at some point of time after key77b (tested on
xorg-xserver-1.20.3), something has changed in the linux graphics
stack that affects keykit's display on Xorg X11 -- it no longer
repaints correctly. This happens on all Xorg Xwayland (on wayland)
across all window managers, all tested only on intel i915
graphics. With some compositors (gnome-shell, weston) initially the
keykit window is painted correctly but adding tools further messes up
the display. (I can't identify what changed but I don't think it is
the switch to "glamor" 2d gl based rendering for X11), thanks for
publishing keykit. -- Best Regards, Madhu"
